1998 Chevrolet C3500 Cheyenne 6.5L Heater
Posted to GM HVAC on 11/23/2007 3 Replies

This truck defrost does not switch on. AC does not work also. All other controls work I've checked everything I know to check. Everthing is new!If u ground the white wire the defrost will work then but I know my grounds are good.
