Blower Motor Resistor: Testing and Inspection
Front Blower Motor Resistor
FRONT BLOWER MOTOR RESISTOR
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 may
result in accidental airbag deployment and possible serious or fatal injury.
NOTE: For circuit descriptions and diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for
the various wire harness connectors, splices and grounds.
1. Disconnect and isolate the negative battery cable.
2. Disconnect the wire harness connector from the blower motor resistor .
3. Using an ohmmeter, check for continuity between all of the blower motor resistor terminals. In each case there should be continuity. If OK, repair
the wire harness circuits between the blower motor switch and the blower motor resistor or blower motor as required. If not OK, replace the
inoperative blower motor resistor.
