A/C Control Problem...
Today the AC unit was working fine, i didnt use it today though, but the part where it shows the air direction was still on the LCD screen. i get back into my car tonight, and the unit lit up with my headlights on and such, but not the part where it shows where the air is going, and there wasnt the green light above either inside air or outside air. I pushed anyone of the buttons and nothing works; air, heater, defrost, nothing. I looked in the manual and fuse number 2 in the driver kick panel shows that thats the fuse that controls the AC system and window defogger. Anyone else experience this? Im going to go replace the fuse tomorrow.

nnnick, I am having the same problem with my Climate Control Unit. The backlight was working, and the air direcection part, but the unit itself didnt work. Sometimes though, It would just turn on and work perfect while I was driving down the road. I checked my fuse, it was fine. I took the CCU out of my car and smashed it (I was pissed). Im having a working one shipped to me. Ill let you know if it works.
