|mmbrock77||Ebay has the part, too. I replaced mine in my '05 TJ. It's behind the glove box. Kind of a pain to get to but it's do-able.|

|BigDaddyAt||Nice. Now I know what has been the issue...and how to fix it|

|ronpete13||Changed mine this weekend - Works again!! - Don't hurt to have someone with smaller hands☺|

|thgr8alex||Ya autozone wanted 45 bucks for that piece. Found it on quadratec for 27|

|Relocatedduckman||It's the resistor under the glove box. Mine was that way. Replaced it.. Boom.. Good air again..|

|thgr8alex||My jeep is doimg the same. Only works on the 4th setting. So i got all or nothing..literally. Hah so i was near autozone today and they said it was 45 bucks. Is that too much for one as i saw on here its a 20 dollar fix or so?|

Replace the blower resistor as indicated. On mine and my neighbors, we lost fan speeds one by one over time.
|05-06-2013 10:28 AM|
Mine works on the 2 higher settings but not on the 2 lower? - 2004 TJ
Thoughts on that....
|05-05-2013 07:56 PM|
Mine went out on a 97 TJ
My fan would only work on high and the switch from floor to defrost had stopped working also. Removing the leaves that had filled up in there fixed the switching from floor to defrost and the resistor fixed the speed control.
What in the world did we do before the internet?

|snow.thrills||I had the same problem in the fall. Only high speed would work, sometimes. I replaced the resister and that didn't work. I almost went the blower route but decided to replace the heater control assembly instead after reading some good posts on this AWESOME Forum. Glad I did it was a 30 min at most $90 fix. It turned out the vacuum switch was shot and the back side of the assembly was a little melted which I think caused the vacuum switch to sit in a bad position and fail. According to some of the jeep parts websites you can replace each one of the heater switches/selectors individually, just another decision you may want to consider. It only takes a few minutes to take apart the dash an take out the assembly. I was able to tell my issue as soon as unscrewed it from the dash. A little wiggle on that switch and everything worked as it was supposed to. You may even be able to wiggle that switch from the glove box. Good Luck!|

Was able to replace fan motor resistor for '99 TJ with a wrench and a new $47 NAPA brand fan motor resistor in about 10 minutes.
Differential diagnosis for faulty AC/heat fan speeds: (1) faulty fan motor resistor, (2) shot fan motor, (3) HVAC manual dashboard control defect, (4) faulty fuses, and/or (5) underlying electrical failure of indeterminant specificity requiring advanced diagnostic workup.
Youtube has several good instructional videos on how to replace the resistor. For example: http://www.youtube.com/watch?v=kikg3uoeNLc

I too just lost all speeds but high. I could smell a slight electrical smell and thought, what is going???? But I read lots of these forums to know what it is. This forum is GREAT!!!!
THANKS to everyone here!!!!

|s3nt3nc3d||Could be a resistor pack, but I'd check the wiring to the HVAC controls in the dash...often times problems like that are due to melted wiring at the switch.|
|02-05-2011 02:20 AM|
i would pull it out and look at it, its a 20 part and not to bad to change it fixed mine
|02-03-2011 08:56 PM|
|Mikiec||What about it only working on the second speed and none of the others? This is on my 99.|
|02-03-2011 07:44 PM|
|Loo||Replaced this in my 04 last fall. Super easy. Glad I did. I don't like blasting the heat or AC.|

|rtiburon||I have a 97 too. Just changed out the resistor/rheostat for the blower last year. Here's a link with pictures. Blower Motor Resistor Install - JeepForum.com Just inside the passenger door under the glove box there's a black plastic kick-stop panel that's kind of a PIA to remove. After that it's a snap.|

|05wrangler||right on thanx alot guys, im goin to go get one tomarow, then off to the deeler for that "E05" recall|
|02-03-2011 06:04 PM|
|Bryangb7||I just went to the local parts store (advance auto) they had it in stock 20 bucks. I asked for the resistor pack and explained the problem and they gave it to me...two bolts and a plug later I have all four settings|

|05wrangler||i have a 05 TJ that is doing the same thing, only working on high, where could i get this relay and what is it called?? how would i got about checking the switch selector??|
|08-29-2009 10:51 AM|
I have the same proble here as Hondarider... ONLY the high speed is working on my blower motor. I checked the switch selector with a multimeter, and I think the switch is ok..according to a continuity test.
I have 97 wrangler... I har it can be the resistor? Where is it? what does it lok like?
Thanks for your help
|07-05-2009 03:40 PM|
|distortedtj||Yep the resistor look like a large relay.. Just unplug the old one and install a new one.|

|marc1kim||The blower resistors are on the passenger footwell right behind the glove box on the blower housing. Mine problem ended up being the blower motor selector switch.|
|07-05-2009 12:00 PM|
|Jerry Bransford||It's not a traditional set of resistors like you may be thinking of. In newer TJs, it's more like a credit-card size plug-in which can't be repaired.|
|07-05-2009 11:46 AM|
|Hondarider||Sweet! Thanks for the heads up! That definitely gives me a head start on the troubleshooting. I'll take a look at the service manual and see wherethe resistors are. I'm sure I can check the circuit with a DMM.|
|07-05-2009 11:09 AM|
|Jerry Bransford||The fan only working on high is normally due to a defective resistor pack. The resistor pack is used for all speeds except for the fan's highest speed where the resistor pack is bypassed. Your 2003 has it in a different location than my '97 does but yours should be somewhere up above the passenger side footwell. It's easily swapped.|

Blower only works on high...
2003 TJ 4.0 5spd. So the heater fan only works on the highest setting...nothing happening on the other three settings. Blower motor or the switch? Has anyone seen this before? If this is a common failure, it might save me some time on the troubleshooting side of things. Thanks.
