Sorry I'm such a newbie, but today my air condition stopped working. I mean the fan won't come on regardelss of hot or cold. I looked in the manual and it says that if everything else is working ( like the rear wiper, powr windows, sunroof, etc) from the B2 fuse, which it is all working, then the problem is probably a blown 30A fuse for the air conditioner and heater blower, located on top of the blower unit. Problem is I have no idea where the blower unit is. All I've done to the car is whats in the sig. I wouldnt think replacing the air intake would effect any of this? If anybody can help me, I'd be appreciative.
