Heater Blower

(1992 Ford F-150)
in Olathe, KS on January 21, 2011
All of a sudden I can't get my blower to work at any speed, any temp, or any position. I replaced the blow motor resistor, but still nothing! I changed the fuse, and all hoses from heater core are hot as well. What could the problem be now? Is it the motor itself or maybe just the switch?

Could be the blower itself, but pull apart that plug to the resistor again and have a close look. Any damage or burn marks on the terminals or connector? Often times the connector is damaged.

I rechecked the wires to the resistor and motor, they seem to be fine. Today I changed out the blower switch as well and still nothing. Also, I tried a trick soomeone suggested... running a direct wire from the battery to the motor. But still nothing!!! It's got to be the motor right?

Yes; or a ground. Because even if you provide direct power, if there is no ground...you have no motor function.
