2005 WK, air conditioning only works on high
Today we were driving home and I had the air on high until we got comfortable and then I turned the fan down one notch and it turned off completely. The a/c only works on high now. I searched and found the common issue of the blower motor resistor on the TJs. Anyone know of a cure on these? Thanks.

I think its a Chrysler issue in general. We have a work van (2001 grand caravan), and it has had the same issue since 2003. Its either all or nothing with the blower conrol...we have had it looked at and none of the casual mechanics seem to have an idea.

Sounds like a blower motor resistor.
And luckily for you, the WK resistor is probably the cheapest one Jeep's ever sold at a whopping six dollars!

Where is the resistor located? I know the one for the TJ's is located under the dash behind the glove compartment area, but dont have a clue on this one...any writeups out there or does someone want to give a brief run-down of the replacement? Thanks a ton.

2004 Liberty A/C only works on high
Hi - I just had the same thing happen to me. The A/C or heat now only works on high in my 2004 Jeep Liberty. Is this also an $8.00 part? Keep in mind I know where my glove box is - that's the extent of my auto repair skills!
Thanks!

Sounds like it could be the same thing. Go to the jeep dealership and get the part, then open your dash, remove the limiting strap so it folds all the way down, and look for the part that matches what the dealership gave you. There are 2 phillips screws holding it in place. Took me all of 3 minutes to fix. Good luck and HTH.

Thanks to this thread, I was able to easily fix this problem when the same thing happened in my 2006 WK. 
But they charged me $11.50 for a new blower motor resistor, so either the price has gone up, or they just charge more for it here in California. Oh well, at least the air is working correctly again. And hopefully this new one will last longer than the original one did!

Mine just went yesterday. Interesting- the dealeships in MI (where I'm from), charge only $6.60 for the part. I'm up here in Maine and the price is $12.00. Nice markup huh?
