Blower motor will only run on high is there a fuse which controls this problem?

SOURCE: Heater Control Switch Only Works on High

I would Replace the blower Resister aka temperature heater fan resister.

SOURCE: my 1998 astro van blower motor only works on high speed.

No the motor is not bad or going bad, the heater blower motor resister is bad, thats regulates the blower speeds, its located under dash by heater motor 2 screws hold in heater box with a electrical plug to it.

THERE'S A SENSOR UNDER THE PASSENGER SIDE OF THE CAR UNDER THE GLOVE COMPARTMENT YOU HAVE TO LOOK WAY UNDER JUST LAY DOWN ON TOP OF THE MATT IN FRONT OF THE PASS SEAT IT HAS 2 SCREWS ON IT UNPLUG IT THEN UNSCREW IT TAKE IT TO THE DEALER IT COST ME ABOUT 30 TO 50 DOLLARS BUT THAT WAS THE PROBLEM I HAD. GOOD LUCK

SOURCE: Blower motor on 96 Isuzu Rodeo does not blow on

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.
