Re: Heat/AC issue... AC sompressor turns on..
AC compressor operation allowed:
AC compressor operation not allowed:
If desired, it is possible to add a dash switch to disable compressor operation. The purple wire from the back of the HVAC control panel tells the PCM when it should allow compressor operation. Interrupting that wire with an on/off switch would allow the compressor to be turned off in any position of the HVAC mode selector dial.
