On your vehicle, if it works on low speed, that eliminates the fuse, the blower motor relay and the blower motor resistor. All of the parts of the resistor must bee good for it to work on low. The relay supplies power to the motor and the controls provide the ground, so if the motor runs at all, it is not the relay or the fuse. The only thing left is the switch. Fords are bad about burning the wire connector that conects to the switch. You will most likely have to replace the switch and the connector. Both of these parts are widely avaiable at most aftermarket parts stores.
Well you got the diagnostic dead on. your blower motor relay is located on the evaporator box and is the plug near the blower motor.
That would be the blower motor resistor, not the blower relay.
The blower relay is mounted at the rear of the engine compartment in the left fender area, near the Ignition Control Module.
yes you are correct. i meant to say resistor and that's why i listed the location as on the evap box. thank you for clarifying.
