AC Blower Motor wont turn on, good blower motor.
91 f250 302, 200k+ miles?? (odometer broken)
Hi, Im looking for some pointers for diagnosing and repairing my ac/heater blower motor. It has never worked since I bought the truck and I thought Id get it working just for a fun challenge and not as much out of necessity.
My knowledge is limited on this topic but to rule out a bad blower motor I removed the fan from the truck and brought it inside to hook up to a battery charger, it powered on a worked great so the problem lies elsewhere, trouble is im not sure what to check next? There is problem somewhere between the dash fan speed switch and the actual blower itself. Thanks for any tips!

The next thing to check is the blower motor resistor ...
It is located in the Heater core box next to the blower motor, look for wires going into the heater core box, the resistor is held in by two screws ...
You are going to want to pull it out regardless to ensure it's not filled with debris.
