Heater blower motor fan won't work in 2003 Chevy pickup half ton. Replaced motor had power on both wires in motor plug. I grounded the black one out now no power on either one. Fuses good


you have a fan resistence it should work in high speed only or not at all check all fuses to be sure you should have a 30 amp for the motor and is the motor new or used try the motor at the battery first to see if working before going further

If it is only working on high the blower motor resistance has to be rplaced it controls the speeds of the blower motor.

I have a 1992 chevy lumina that only the high on the heater control works. i have replaced the control panel the blower module checked the blower motor still only works on high.


either the switch or there is a resistor pack in the heater duct that gets burned out and only 1 side works if it is not the high medium low switch check resistor pack mounted in the heater duct.

My Blower motor for my heater on a 99 ford escort is not working.Is it the motor or resister that is gone??the fuses look ok where is the resister located can you send a diagram


look in passenger foot well on blower case for 4 wire connector.



Behind right side of I/P, A/C-heater plenum


resister bad would still allow high speed. may be blower motor.

  • The blower motor does not operate/does not operate correctly
  • Open fuse.
  • Tripped circuit breaker.
  • Circuitry open/shorted.
  • Heater blower motor switch (18578).
  • Heater blower motor switch resistor (18591).
  • Blower motor relay.
  • Blower motor.

The heater fan on my 98 chevy silverado stopped working... worked on high at first but made a high pitched noise and stopped all together


Run 12V directly to the motor and see if it will run, if it dosent than the motor is bad, if it does than the resister is bad, the resister makes the blower run and also regulates the speeds for the blower, but chanses are if it was making a high pitch squeel before it quit the motor went out.

Heater works but fan doesnt work


on the inside of the fuse box door there is a list of what each fuse is for, fuses will be numbered with coresponding numbers and explanation of what there for. also if fuse is ok, chanses are its the resister, its located behind glove box on top of heater box 2 screws hold it in heater box, electric plug with 4 or 5 wires going to it. i just went thru this with my 1995 chevy 1500 pick up. but before you go thru that chk. fuse, chk motor, run 12 volts direct to motor see if it works. now did the motor just quit? or did it work on a couple of speeds before it quit? well at any rate if the motor runs when 12 volts are put to it odds are its the heater resister.

IS the problem no heat? If that is the case check your themostat
