My fan only blows on high.

Does anyone know why my fan motor for my air conditioner / vent would only blow on high. Low and medium dont work.

Thanks,
Adam

Yeah, that's pretty common with these trucks. You need to replace the switch, the one that has the 3-4 speed selectors.

EDIT: OK, maybe not the switch, but the resistor. It's an easy fix.

The glove box is pretty easy to get to; 4 screws and a bolt. Apparently resistor's behind the blower motor.

yes the resistor is the problem. When they do fail that is what happens. You have only max fan speed
