Blower Motor Power Module

BLOWER MOTOR POWER MODULE

Models equipped with the optional Automatic Temperature Control (ATC) system have a blower motor power module. The power module allows infinitely variable blower motor speeds. The power module is mounted to the heater-A/C housing, under the instrument panel and just inboard of the blower motor, in the same location used for the blower motor resistor on manual temperature control systems. It can be accessed without removing any other components.

The power module output to the blower motor can be controlled manually by using the blower motor switch knob on the ATC heater-A/C control panel, or automatically by the circuitry of the ATC controller. In either case, the ATC controller sends the correct pulse width modulated signal to the power module to obtain the selected or programmed blower motor speed

The power module cannot be repaired and, if faulty or damaged, it must be replaced.
