REMOVAL
WARNING: 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 an 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.
1. Disconnect and isolate the negative battery cable.
2. Reach under the instrument panel near the blower motor (5) and disconnect the wire harness connector (2) from the blower motor resistor (4).
3. Remove the two screws (1) that secure the blower motor resistor to the HVAC housing (3).
