Well, I tapped the knowledge of an ASE Certified mobile mechanic I use here in town and finally got an answer to my heater control valve solenoid. He look at the heater circuit wiring diagram and came to the conclusion that this solenoid is ultimately controlled by the ECM. He told me that I could spend the buck to figure this out, or use redneck engineering to fix the issue--I am choosing the latter. The heater control valve was not getting vacuum to operate. If you trace the vacuum line up it connects to a solenoid on the firewall. The two-wire electrical connector (black ground, and black grey hot) does not have any power at all, regardless of which heater control panel I use--front or rear. The mechanic suggested putting a switch in to control this solenoid. I already have a single pole double throw switch that I had wired for two backup lights. I could put a single pole single throw switch in if the other switch cannot be used. How would I wire this? What amp inline fuse would I need? The black wire on the switch has a good ground. Could I tap the hot wire used coming into the switch I am using for the backup lights? Would someone have a simple wiring diagram they could explain so I can get this thing hooked up so my kids have heat in the back and my windows don't fog all winter long. Thanks.
have the same problem?
