heater fan wont blow on high

1-2-3- is fine,took the resister out couldnt really see burnt place,is this the common cause? dont have a ohm meter. ed

On the high setting the resistors are not used. They only are in the circuit for the lower speeds. Since the blower works then this would leave only the switch position or the wiring to the blower as the possible problems.

thanks glen,it worked only a few days ago,so im not sure whats going on.is there a fuse for high fan? ed

I just went through this with a Ford Explorer. The resistor only allowed the blower to work on high, then the blower motor eventually crapped out from running full blast all the time. It was $286 to fix from the local garage.

No, there isn't a seperate fuse for the high setting though after looking at my manual for an '88 model it shows fuses 1 and 2 supply power to the circuit (I never noticed that before). The print shows that the switch makes a ground connection to run the motor so you should be able to just ground the high switch position to check the switch and the motor. If that doesn't work, then the wire to the motor has a bad connection somewhere.
