    Question. I have the same problem with my heater fan or motor working on high sometimes. Where exaclty is the motor and resister under hood, or inside by the passengers floor board?
    What does the resister look like, and are these parts bought at the junk yard or at a auto parts store?

    The resistor is located behind the window washer reservoir and the over flow reservoir on the right side just below and to the left of the blower motor. Just follow the blower motor wires right to it. And by the dealer one as it will fit properly. $60?
    It has 2 small screws on either side and hard to reach.

1998 Astro Van Heater AC Blower only works on medium & Low


Yes, in high it bypasses the resistor and uses a high blower relay. But I think on 1998 Astro the High relay and the resistor are built together. It should be mounted in the blower box real close to the blower motor.

Motor heater not working on low and sometimes on high


Blower/Heater Switch Operation: 0900823d8004c694.jpgThis electrical switch, located in a fuse or breaker protected circuit, controls the rpm of the blower motor through a series of control relays and a rheostat. Sometimes the A/C compressor clutch is energized by this switch.
