As there are continous request postings about the A/C blower issues on the 1st generation durango forums, I will post the fix here so all new users will be able to see it first before they post it in the forums.
If you have a 2001-2003 Durango and your front fan motor is working on high speed only (common issue) or not blowing at any speeds, chances are the resistor pack is blown. This is a known common issue for the 2001-2003 Durangos with the new redesigned dash and interior. This resistor pack is a dealer part item only. Cost is around $13-$20 and is a easy do it yourselfer. The resistor pack is located on the passenger side. When you look there, look towards the center part of the dash and you will see a wire harness connecting to the air vent duct. You will need a 7mm or 8mm socket with a u-joint shaft as one of the two screws may be hard to get access to using a straight extension socket shaft.
1. Unplug the wire harness.
2. Remove the two screw and pull out the resistor pack. You will notice on the replacment pack, it looks like a flat square resin pack. If you cannot pull it out, you may have to wiggle it out as I have seen some resistor packs that blown have swollen and hard to slide out.
3. Slide in the replacement resistor pack. Re-install the two screws.
4. Re-connect the wire harness.
That's it. For first timers, this may take you 20-30 minutes. But once you get the hang of it, the actual job will only take less than 5 minutes.

two things, 1, when you change your resistor, make sure your wire harness isnt damaged also, or else your new resistor will blow in seconds.
second, i had the problem that my wire harness was fried too, and i cannot seem to find anything on replacing the wire harness. i tried to take out the glove box, but there is a panel behind it and im not sure if im going to have to take out the whole dash, which i really do not want to do.
It's a fairly simple replacement. Looking through the different posts, it looks like the part number may have been superceeded/changed since I replaced mine back in 2003 I think it was. Didn't think it was going to be that common of a problem when I created the page, but looking at my site stats, I average about 3-400 page visits a month on my resistor page.
I, of course, had the same problem happen to me recently. I read your fix and followed the instructions, and within a matter of minutes, had my fan working properly again. Thanks so much for the info. BTW, it only cost me $15 Cdn for the part.
Along the same topic, my blower fan in my 00 operates at all speeds, butmuch slower than normal. At the lowest setting the air coming from the vents is there, but just barely. At the highest speed, the air comes out at what I would call medium. The air is coming out of the proper vents, in other words, not being mixed with other vents making it appear that the air volume is reduced. I did not see this previously discussed (other than the blower not working at all at various speeds - mine does, but slow) and I apologize if it was. I am leaning toward blower fan bearings going bad as opposed to a resistor problem. I would appreciate if anyone has an opinion/experience. Thanks!
Thanks for the reply Mean Green.
I agree that the high is not very high, I noticed that in my 99 and my 00. But over the last 6-9 months or so the air volume dropped significantly. I figured for the price I could change the resistor and see if that is the problem (not much $$ lost if it is not), but I do not want to pull the dash for the blower if I do not have to. I am just not sure if there could be another problem (other than blower or resistor) that I am not thinking of...
Has anyone replaced more than one of these in a couple of months? I think I had one go on my 02 while under warranty a couple years ago. That one lasted until Dec 06. I replaced it, the replacement went in about two weeks, got another and the parts guy told me at the time that it could be my blower motor causing the problem. After three weeks, my third one went. WhenItook out the last one, some water was dripping from it. Strange?
Wow, this worked great. I had called a local repair shop and the fellow explained that this happens all
the time. He stated that sometimes the wiring harness goes also and the fix would be around $400.00.
I figured I better check this out myself, found this place and rest rest is history.....total cost $11.99 w/tax
and about an hour of my time.
One other thing I thought you guys might find useful. The wire harness somehow was getting water on it which travelled down the wire and into the plug on the resistor pack and it caused the wires to corrode. Eventually the one wire actually rusted enough for it to separate from the harness plug. So FYI you can buy the harness end with about 1ft. of wire. It comes in a kit for about $25CDN. Simply cut off the old harness, I had to cut it cause mine was corroded so badly I couldn't pull it off the resistor pack, attached thenew wires to the old and voila! Works Mint!!!!!! Hopefully this will stop my frequent resistor pack failure.
