This scenario is the same for pin 5 with the Med 1 position. Look here for the "how to" with pictures. Then a couple days later it’s melted again. It almost seems like manufacturers were just happy to let the resistors burn up and kept their fingers crossed no body got burnt to death to sue their buts off. The Dodge Dakota (called the Ram Dakota for its final two years of production) is a mid-size pickup truck from Chrysler’s Ram division (formerly called the Dodge Truck division). heavyduty April 15, 2018, 5:36pm #6. Good luck. Replace the blower motor resistor and module connector using the following procedure: Remove the blower fuse. After years of replacing the blown resister module 3 to 4 a year, I finally bit the bullet and bought a … So I got it exchanged and popped the new one in earlier this week. I have had it replaced three time in the last 2 years. 2004 Dakota with 4.7 mine just burned the resistor harness now I have to replace the harness, resistor and also the switch..i took the switch apart and the circuit board is burned out the fuse itself is good so the circuit board failed, 01/16/2019 by You would think that they would rate the fuse to blow before it got to the stage of melting the wiring and possibly starting a fire, due to high current flow caused by a faulty blower motor. Mostly on the trucks. When it burns up, will only work in high. The cowl panel is the long plastic panel under the wiper blades/arms. Hopefully it is the same for your particular year model. Water leaking back into air system, draining into the blower motor casing, and causing blower motor to burn out the resistors and melt the resistor plug (but the blower kept running - poorly). Good point AnnMarie. This time, it all went out without warning and wouldn't even work in high!! So what is causing the resistor to burn out? It is always the second pin on the harness that melts (tan wire). It died again this morning. When I replaced the resistor connector and wires (melted) I took the blower off the truck . Does anyone see any issues/downsides to this workaround? It all stems from a/c drain design flaw. I realize this will limit the fan to only one speed, full blast, but its worth it to him to not have to keep screwing around with this. Midsize Utility Vehicles - Blower Fuse 35 located in the Underhood Fuse Block. Although this isn’t as common, the chances of this happening increase if you have a melted electrical connector. Lower the hush panel or close-out … Given the figures quoted in the video why would they still install a 40A fuse in a circuit where the current draw for a good blower motor is 18A and it was causing heat problems at 23A. A common cause for these failures is that water is getting into those components. Even if you use 100% OEM parts it still fails: The reason is………….For your 2001 to 2011 vehicle MOPAR didn’t make your replacement part. I hope this helped you out, if so let me know by pressing the helpful button. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The usual cause of repeat failure is the blower motor draws too much current upon starting, the connector is burnt or melted or the replacement part is inferior quality. What could be the reason it keeps going bad? Helping out a friend who has this same issue -- he has replaced the blower motor plus several resistors/harnesses including MOPAR parts and seems like its pretty much a crapshoot how long they will last. Note that the resistor is in the duct where the blower discharge is blowing on it all the time when running. and rotate the switch. Hopefully I have not confused you with all this. Thank you for input totally appreciated it, 04/01/2020 by The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. It will only operate on a full s/c. My 1998 Chevy Malibu blower motor keeps going bad. Mine quit and moving the connector caused it to make better contact and it would work for a while. It’s made buy a number of after market companys, mostly NAPA. I've had it replaced 3 times in 3 years, and today it … Sorry, not the perfect fix but it is the truth, I’ve spent 2 years figuring this out. My hose was cracked. Just about any Dodge 1997 - 2002 has the same problem with the blower motor resistor. heater blower, resistor keeps burning up? They are turning the wiring into fuse wires. With that said, if the blower motor doesn't work at all it's also common to find a defective blower motor relay. The solution was to buy a new wire harness kit, get yet another new blower motor resistor and replace the front blower assembly. Then they buy a aftermarket blower motor and again it keeps burning up. If the blower motor looks like it is rusty, or the resistor keeps burning up, then it is most likely water intrusion. If not then it may be a faulty blower switch. Replaced my blower motor because it was noisy.....that fixed the noise problem; however since that time my blower motor resistor keeps blowing. The blower motor draws too much and causes the resistor to fail again. As the blower motor runs, if a bearing is worn, it will seize up after getting hit, then this causes extra resistance and this will cause the resistor to burn out. Have you had any time to pull the blower motor and lube it up and make sure it works with out any drag? http://dodgeforum.com/forum/1st-gen-dura... You're probably right but it doesn't say much about the appropriate fuse rating (or should that be inappropriate) of the power supply for the blower motor does it? usually when the blower motor gets old its starts to draw more current to run. Here is a the blower circuit for a 2002 Dodge Dakota. Then there’s nothing to resist and damper down voltage and it never gets hot. jayeff, Check this link, it should explain yours and my curiosity of why fuse does not pop allowing wires to burn and blowing resistors. The wires will burn out before the fuse will. If the coils are burning up, they are seeing too much resistance. Excessive current flow, maybe a short to ground between resistor pack and blower motor itself. Blower switch on non AC '69 keeps burning out. The blower capacitor is weak causing the motor to overheat (a good tech would usually replace both the motor and the capacitor after a motor failure). I did soldier each wire from the resistor plug . Replace everything or soldered wires to resistor to no avail. The Blower motor resistor in my plymouth breeze keeps burning up. Why hasn't NHTSA recalled here? Oh sure it will say MOPAR on the box and say factory original OEM part, BUT IT’S NOT!!!!! With the plug disconnected from the resistor measure back toward the switch between the wires for pin 3 & 4 (light blue and light green/yellow) and 4 & 5 (light green/yellow and tan). Have not actually seen too many connector problems on the older Malibu's. 6 weeks ago I replaced my blower motor and blower motor resistor. Noboys makes their own parts anymore, mostly China crap. Thanks for the interest, I wondered why also. And then it works, but only for a year and then it burns up again and you say what the F#*@!!! Need to glue that strip back into place to fix the water leak problem. Retro the resistor to get better connection and problem solved. Specifically, the problem resides in the wiring between the resistor connector and the blower motor, which could also lead to the aforementioned burning plastic smell or smoke. I replace it 3 times will work for a day or two in all fan speeds. Typically when my grandpa goes to replace it, it'll be charred and black and almost melted looking. I kept replacing them and they kept burning out but while they worked 3 and 4 came back then I would lose 4 and eventually 3 (within a month of new install). Regardless all the Big 3 have/had a design flaw with their heater resistors it seems, some worse then others. I finally found the simple solution and ultimately the actual cause to the issue of the blower resistor burning out and over-heating the plug wiring - The blower motor itself is the culprit! It happens again. Good thing it isn't very expensive! Like hard hat said, the blower motor may be the problem (and will burn out the resistor again). The FSM will tell you what it should be. Dakota Fan Hope this helps someone with their problem . Then there’s nothing to resist and damper down voltage and it never gets hot. This is because this is the resistor which carries all the current when the switch is in positions low thru med 2. It may be the blower motor itself has bad bushings or some such thing. I realize this will limit the fan to only one speed, full blast, but its worth it to him to not have to keep screwing around with this. Worked like new until last week when the new resistor died already. long that is suppose to be attached to the steel lip just below the windshield. From the passenger side fender, you can lift that panel from under the hood and look for a black weatherstrip about 18 in. I'm thinking a defective blower motor that isn't cooling the resistor as it should. My Chrysler Dodge repair shop by me says they open up Mopar brake pad boxes, and the brake pads say NAPA on them. which can pop fuses, burn out resistors and melt wires. A lot of mechanics don't bother to troubleshoot the resistor failure, they just replace the component and move on. Hi folks. Go to Edmonds.com with samequestion. The double orange has one of the wires going to the blower motor and the other orange wire going to the heater resistor assembly. Replaced the resister ONCE AGAIN, and it works!! Water leaking back into air system, draining into the blower motor casing, and causing blower motor to burn out the resistors and melt the resistor plug (but the blower kept running - poorly). I would like to test it to see if it is out of spec before I replace it. If there is no strip at all, then there was not a seal, and the cowl panel to windshield will need to be sealed with silicone or other sealer. A usual place for water to enter into this area is a loose, or missing weatherstrip under the upper cowl panel. Thousands of people have the same problem with their dodge. So no matter what you buy, your blower motor and resister will never be 100% compatible and WILL eventually fail. Hi should not affect it as it is a short circuit through the resistor anyway. Figure 3. It's possible for the electrical failure of the blower motor resistor to take out one or both of these fuses as it melts. The motor is undersized. Checked other things first (since the blower motor was fairly new (fuses, relays, etc. Noticed moisture on blower cage. A usual place for water to enter into this area is a loose, or missing weatherstrip under the upper cowl panel. Bypassing or adding a relay to keep blower motor resistor connectors from burning out. Only use high speed fan setting for heat and AC. Jump to Latest Follow ... has the blower motor and resistor easily accessed. Only use high speed fan setting for heat and AC. Chevy it don't matter you know but I wish I understood the pain solution so I can figure that out cuz I am burning up in on the resistors which means it's getting too hot hi guys you did you doing a great job thanks a lot for a guy that you're working on 40 cars for 40 years, 09/16/2019 by Think I need to solder each wire. Fix leak. Dennis Smith, Only mine to 05 Monte Carlo with a 3.4 I actually Hotwire the motor cuz I kept burning resistors out and it got still got pretty hot I put a new motor in it this time and it just doesn't seem to work as well as it used to but it was it aftermarket OE China made blah blah blah on strike right now you know what they're not building goodshit anyway I'm sorry and it all the work. If you leave the blower motor switched continually on you may not notice this. Then again if your resistor appears burned or melted you may need to replace the plug with the wires (the wiring harness) and the resistor and probably the blower motor. Does anyone see any issues/downsides to this workaround? Unfortunately, the wire harness has to short several resistors before the mechanic starts to see that something is wrong. It seemed that it was a little hard to spin on it's own . BUT I am having this same issue. It is a part that should have been recalled by Dodge the first year it came out. Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life. When your Dakota or Durango left the factory, it had a Mopar motor and voltage resister that were compatible with each other. I had this problem reoccurring! ), all seemed ok. This is a Video of one of the reason why we have to change this Piece so many times. So replacing both the blower motor and resistor at the same time fixed the problem. Does the blower motor run with the switch in the OFF position? I am amazed that they allow such a large tolerance. Or the cowl panel is not sealed well against the windshield. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. These have been recalled in Canada. @dakotafan. Matt Bennett. 2. We've had codes checked and it said it led back to the tranny?? My motor works but keeps melting the connector to the fuse. Hi..as I said the damn heater blower and resistor keep burning out on my intrigue. Next time water poured from the motor housing (worked 1 mo ). Just the way it is today. Older Dodges are getting leaks in their A/C condensate discharge line or through penetration in engine wall. You can even use cheap eBay parts etc. That's where I would have to start at and make sure the blower has a good ground. If so I suspect that there is an earth fault on one of the wires connected to either pin 4 or 5 of the resistor. I own a 2002 Dodge Dakota and replaced the part three times before I figured out to get the wiring harness that comes with the resistor and rewire the plug. Does anyone know the current draw specs for these motors? Blower Fan Speeds Not Working On My 2002 Chevy Impala, Chevrolet Malibu Overheating Even After Engine Replaced, Location of Blower Motor Resistor On 2001 Chevy Silverado, Location of Shift Control Solenoid in the Transmission, A/C Vents Blow Cold on Passenger Side But Warm Drivers, Engine Noises | Knocking and Ticking | Common Causes, Engine Dies and Then Starts Right Back Up, Dodge Avenger 2.4L Crank Position Sensor Location. 06/14/2017 by If you've read the comments in the answer below, since you have to replace the harness etc, perhaps you should consider connecting an inline fuse on the power supply feed to the blower circuit as well so as to protect the harness etc in the event of the blower motor going low resistance (shorting out between motor windings) in the future and burning out everything before the designated fuse can operate. Like I said, there are multiple videos and forums discussing this A/C condensate leak back into the vehicle and how to repair that. Or the cowl panel is not sealed well against the windshield. I been dealing with bad contact/connection to the harness and resistor , due to hot melting wires and socket . Sep 25, 2017 | … If the motor draws more current than the engineer who spec’s the resistors thought it did, this effect would be worse, and the resistors would burn out quicker. Replaced blower motor, resistors, and plugs multiple times. The warranty covered the initial replacement but otherwise I am getting nowhere. HVAC Blower Motor Resistor - Compatible with Ford, Lincoln & Mercury Vehicles - Expedition, Escape, F150, F250, F350 Super Duty, Mustang, Mark LT, Mariner Replaces 3F2Z-18591-AA, YH-1715 4.6 out … 05/30/2019 by To check the blower motor for bearing failure, pull it out of the heater box, leave the wiring hooked up, run the system as normal and keep an eye on it. If you look into the female end of the plug you will see black in one of the holes where it blew out. I'm thinking my blower motor is drawing too many amps and burning out the resistor. terrywoodward74. 2 people found this helpful. Hi jayeff, Definite design flaw. If that weatherstrip is hanging or fell off completely, then you have found the leak. Still dealing with condensation discharge , as it keeps into the cabin , under the carpet . A half watt resistor would burn out to prevent further damage while the 1 watt or bigger might allow too much current to flow through another component. Blower Motor Bad Not Resistor - ChevroletForum.com My wire harness melted. Just the way it is today. I'm wondering if it is good/feasible solution to just bypass the resistor/harness and run power directly from the fan switch to the motor, through a fuse -- like this: https://ibb.co/iBC7qV. I'm replacing the connector and couple wires. The second-generation Dakota began development in 1991, though they were not introduced until 1996 for the 1997 model year. I put lots of WD-40 aot both ends and that makes spin much easier . Noboys makes their own parts anymore, mostly China crap. I got in my truck this morning and had some frost on the windshield so I turned the defrost on, blower motor … Check that and the plug up to the blower and resistor for any melted wires. cheap replacement from Autozone / Advanced etc. The one thing that caused mine to go bad was leaving the fan on when I shut the truck off, next time I started it, it blew the resistor. Thanks for the input ! Fullsize Trucks and Utility Vehicles - Htr A/C & HVAC 1 fuses. It is located under the glove box, it takes about 15 minutes to fix and costs about 20 bucks. 11/03/2019 by Check the motor draw when it is on high. Susie Whitacre. Oh sure it will say MOPAR on the box and say factory original OEM part, BUT IT’S NOT!!!!! Many Dodge forums tell of this problem. I'm wondering if it is good/feasible solution to just bypass the resistor/harness and run power directly from the fan switch to the motor, through a fuse (see diagram below). Accessibility. Ok , think I figured it out . It starts out slow and you figure there is something wrong with resistor, resistor connector (which melted) or the blower motor's old, or they-don't-make-these-blower-motors-like-they-used to. Edward Wong. Green eyed baby boy. Damaged wiring on the right side. In my experience, the blower resistor shorts out due to an open in the pigtail harness. Huuuuum ! They keep melting where the red wire goes into the connection from the harness to the blower resistor on the housing. After 10-15 years the motor wears out , begins to draws more amps burns up the resister. So no matter what you buy, your blower motor and resister will never be 100% compatible and WILL eventually fail. It starts out slow and you figure there is something wrong with resistor, resistor connector (which melted) or the blower motor's old, or they-don't-make-these-blower-motors-like-they-used to. Terms — You can even use cheap eBay parts etc. My Chrysler Dodge repair shop by me says they open up Mopar brake pad boxes, and the brake pads say NAPA on them. If you are using aftermarket resistors try one from the dealer, inspect the harness connector for burning or melting of the connectors or housing and do a current draw test on the blower motor. I suspect that there will be no reading between pins 1 & 3. It seems the blower it's from a junk yard . The blower motor resistor was burnt out. 09/10/2019 by Most people replace the wiring harness and the resister with. I am going to wire in a fuse before the connector that keeps burning up. So the resistor gets hotter at the lower speeds, and burns up faster. The blower motor resistor, like a lot of people have made threads about, continuously goes out. There is a post I did some time back on the blower motor showing how to remove it and clean it. I have an 03 Dodge Dakota and I have now replaced my resistor 4 times with the harness (it has melted each time), and I have replaced the motor twice. Figure 4. Parts used - Scitoo Blower Motor - Resistors do not burn out first. That is why the resistor keeps burning out. It’s made buy a number of after market companys, mostly NAPA. Before I could tell when it blew, because it would only work on high. The reason is………….For your 2001 to 2011 vehicle MOPAR didn’t make your replacement part. I finally replaced the blower motor and was fine for about a year. However I am suggesting that if for example you had an wiring earth fault on pin 4 and the switch was on Med 2 then not only would you have the normal current flowing through the resistor connected between pins 1 & 3 BUT you would also have more current because of the circuit path available thru pin 4 (which shouldn't be there).
