The heater control valve is not opening. There is no vacuum to it. There is vacuum to the HCV solenoid. The solenoid has ground but not power. I do not know which wire in the climate control unit in the dash should feed this, nor do I know if it is a direct feed, or if it goes somewhere else first. Fuse 12 is good. Suggestions and a good wiring diagram would be appreciated. Thank you.
have the same problem?
