the blower resistor is an electrical issue, its wired before the blower motor and is not part of the blower motor. the control head sends ground to the blower resistor on 4or 5 wires depending on the number of speeds you have, depending on the speed selected different resistors are used internally in the blower motor resistor to chage the blower speed., check the fuse first and then most likely youll need a blower motor resistor as they are common issue on all vehicles.
below is the removal procedure for the blower resistor.
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury or death.
WARNING: The blower motor resistor may get very hot during normal operation. If the blower motor was turned on prior to servicing the blower motor resistor, wait five minutes to allow the blower motor resistors to cool before performing diagnosis or service. Failure to take this precaution can result in possible personal injury.
CAUTION: Do not operate the blower motor with the blower motor resistor removed from the circuit. Failure to take this precaution can result in vehicle damage.
- Disconnect and isolate the negative battery cable.
- Remove the two screws (1) that secure the trim cover (2) over the blower motor resistor (3) located below the right side of the instrument panel.
- Remove the trim cover.
- Disconnect the wire harness connector (1) from the blower motor resistor (2).
- Remove the two screws (3) that secure the blower motor resistor to the front HVAC housing.
- Remove the blower motor resistor from the front HVAC housing.
