My heat/ac controller doesn't work.. I know this problem is very common within this car.. I usually just turn the levers manually, but I was wondering if anyone can tell me how to fix it.. It's a pain reaching under the steering column to change the temp..

 

there is a "TSB" that explains how to change it out so that it works and doesn't break in the future. I don't know where that TSB is though, and haven't seen it in a while....i'll try to search for it, but you may find it before i do

The reason I never did it is because the TSB says to drain your refrigerant, and I don't know how to do that without taking it to a pro.
