Re: Adjustable temperature switch
If you have a pick and pull, any Ford Escort from the 80's has a fan switch at the end of the Tstat housing. 1 wire grounding type switch. Turned fan on around 200. Other electric fan Fords had them also but can't remember location of them all. Mid to late 80's Mustangs with 4-cylinder electric fan had sensor in the heater supply hose.
