hey guys my friend has a gtp that is electrically fukked.....his hvac get no power at all most of the time.....sometimes it flickers really fast in and out when the car is first on then dies out....the wires behind the hvac have been cut and wired back together so i checked them all and they are matched correctly....dunno why someone cut it but whats your guys' guess im stumped all fuses are good...anyone know which color wires on the hvac harness supply the power and ground? does the bcm have anything to do with this because his auto/drl lights are all out of wack too....btw multiple hvac have been tried and they all worked in my car....
