Blower Switch
WARNING: This page is about a different car, the 1995 Ford RV Cutaway, 1995 Ford Econoline, 1995 Ford Cutaway, and 1995 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.
A 4-speed blower switch is positioned on left side of control panel. See Fig 1. A thermal limiter is part of the blower motor resistor circuit. If thermal limiter temperature reaches 250°F (121°C), circuit opens and blower motor becomes inoperative in all speeds except HI. If thermal limiter is blown, blower motor resistor unit must be replaced.
