Question How do I get the ACC to move off of vent? Hot and cold air only comes out of the vents ,nowhere else.The different switch's on the ACC control light up.I have had problems with the blower motor stopping also. The compressor for the air does cycle correctly.
Answer Sounds like the ACC computer is misbehaving. Try pressing VENT and AUTO simultaneously. The ACC computer should run about a 40 second diagnostic check. To display the fault code(s) press VENT again to cycle through them. I can send U a list of fault codes, Email me at rlmieras@telusplanet.net
The fault codes for air distribution are 6C (short circuit) or 6U (open circuit) indicating that your air distribution servo has died. I would not be surprised if the Computer itself is at fault, however.. Code EU
