I bought a 1989 ford 150 and the switch when you turn on the fan won't blow. The one control Air Cond and Heater. I been told it could be a relay somewhere under the hood. Or it could be switch inside the truck. How can I be sure which one. The truck is V8 351 engine with air and automatic tranmission.

Do any of the speeds work? Also, have you checked to see if there is power to the motor?
