Blower Motor Switch Resistor Assembly







The heater blower motor switch resistor is located on the heater plenum chamber case, next to the blower motor in the engine compartment.

Removal and Installation

1. Disconnect battery ground cable.

2. Disconnect the wire connector from the heater blower motor switch resistor.

3. Remove the two attaching screws and lift the heater blower motor switch resistor from the opening in the heater plenum chamber case.

For installation, follow removal steps in reverse order. Check system for proper operation.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

Blower Motor Thermal Limiter

The blower motor thermal limiter is a non-serviceable component which is part of the heater blower motor switch resistor. If the heater blower motor switch resistor does not pass a continuity test, the thermal limiter has blown and the entire unit must be replaced.
