A quick question...the blower on my 2002 SLT+ does work on all settings, however, it isVERY weak on the lower 2 (so much so that I end up turning it to almost high all the time to get air moving) [&o]. Would this blower resistor also take care of that?Or is it only if you entirely lose blower function except on high setting? Thanks for any info.

 

It's the resistor, I had the same problem. Now we only use the first two setting now. What a difference it made.I paid $8.17 + freight from OEMDodgeParts.com..

 

Perfect...thanks...I'll swap it out.

Just thought I'd give an update: The swap out took about 1 hour (as I didn't have the flex socket and had to finesse it out). Anyhow, the old one looked "cooked" and the new one went in without issue. I now have ALOT more air movement. I should have done this years ago but just assumed that the Durango was always weak in this area. On a side note, we get hosed up here in Canada. The part was $28.75 from the dealer. The same part is $9.23 online in the States. What a rip.

 

I have read and re-read all of the threads relating to this subject and wanted to provide some feedback/information that I have learned over the last year. I have, in the last year, replaced 5 BMRs. The guys at the dealership are sick of seeing me because I have had each one replaced under warranty. They keep telling me it's the Blower Motor, not the resistor. I also happen to own the Durango shop manual which describes in great detail how this resistor lowers fan speed by incrementally increasing the resistance to the lowest blower speed (meaning the blower defaults to the highest speed when the resistor fails). The motor (unless it is faulty) does not create resistance, so the problem should, most of the time, not be the motor. Instead, more likely it is a damaged or burned connector. I bought a replacement harness ($80) complete with a new connector plug, soldered in the new wires, as the maintenance manual prescribes, and all worked well for about 3 months. In the last month, I have replaced the resistor 3 times. I am getting so good at it that I can do it in the dark (which is pretty close to how you have to replace it anyway). Worse part of all of this is the damn back ache I have after laying under the blower housing upside down. My question now for all of you experts would be why does the damn thing keep blowing in the first place. No ground, no open circuit, proper resistance in all speeds when checked with a digital multi meter. No obvious culprit. I hate the idea of replacing the blower motor just because the guys in the parts dept. at the dealership tell me to. All maintenance literature points elsewhere. Is there just an inherent problem in the way these resistors are designed? If so, where's the freaking recall? Thanks in advance for any input.

 

The resistance in the motor is to high, thus blowing the resistor over and over. I'd say they are correct.

No, if the resistance of the motor is set too high, it will never blow the resistor pack, the motor just won't spin as fast. Now if the motor is approaching a dead short, then it will blow the resistor pack as it will overload it.

One thing that was mentioned in this thread is possible moisture problems. Some users have reported that the moisture buildup from the A/C coil was running off and dripping onto the resistor pack. Some even stated that the moisture was wetting the harness connectors that can cause early failure.

Check to make sure your A/C system has good drainage and shows no signs of wetness anywhere near the resistor pack and harness.

Otherwise, you may need to do a load test on your fan blower to confirm it may be shorting out?

I have gathered a ton of info from these posts. I am not sure what is causing the resister to go bad. Our local parts store has sold several, so don't have to go to the dealer. Keep up the good work. Happy riding and driving.

Make sure you get one with a current date. I got one from dealer stock and Manfacturer date was 12/07 so I would not recommend earlier than this. Apparently the newer resistors come up that supposedly last longer. I have a dealer appointment Monday for r/r harness and resistor. My harness is apprently an overload and is causing resistors to blow. Fortunately it works on high but enough is enough. I need to get it fixed before winter, so dealer visit is on.

 

Well as expected it failed again. This time it failed real bad, the high speed and power wires insulation was worn away right up where the pins seat to the connector. This caused them to ground against each other, shorting against the resistor and fusing the resistor to the connector. Of course this led to two replacement items. It took a while but I found a donor vehicle. I had to replace the wiring harness again, but fortunately I had a spare resistor brand new in the box. The donor vehicle was a Dakota but same vintage and schematics/ wiring harness matched. Cut, splice tape,ziptie and ops check. Works in all speeds, all settings. Another dealer visit averted, and I think I have it this time, I checked the wiring harness better this time, and have full insulation against the pins on all wires. I do have a extremely long length of wire, but I am worried about function over cosmetics. I will tuck it up better later but it works now. Just in time, there was a light layer of frost this morning on my way to work.
