Heater Control Valve Elec. terminal?
Any idea where I can find the screw-in electrical terminal for a heater control valve? I think I read it can be just be grounded out, as it only shuts off the HW flow during air conditioning. Screws into the end, and has a spade type connector that mates with the one draped over the valve in the pictures. Thanks in advance.

You're looking for GM part #6490081 (if it's the one-terminal switch).
It is sold by Airtex through the usual outlets as Airtex #1T1040.
You can get it for $85, $50, or $36, your choice, or you can just ground that wire to leave "Low Fan" permanently enabled and be done with it.

Grounded: You have all fan speeds, Low through High, all the time.
Open: You have all fan speeds when the engine coolant temperature is above 40°F, below that you have no Low speed.
