No it appears that I am getting a ground when at the "max" position, which is letting heat flow..but heat continues to flow even when wires are unplugged....so maybe the valve is stuck open now.
But why is it getting ground when the wheel is at "max". Since the voltmeter inputs are connected only to the red/black and brown/white wire it should be reading 0v if the sensor is not connecting to ground at "max".
I'm going to pull the valve out just to inspect it at this point and see if anything is obvious, if not I'll let my mechanic fool with it at this point. Nothing is ever an easy fix on this car it seems.
