Re: One other thing

Looked up the heater control circuit in the service manual and there is no relay, just a fuse, a 2A in panel A605 in the center of the dashboard behind the radio. If you have 12V at the control valve with the temp control in the full hot position then the fuse is good. If the voltage goes to 0 when the control is turned to the full cold position then the problem is definitely the heater control valve.
