Control Module HVAC: Description and Operation
Front Blower Motor Power Module - Description
DESCRIPTION
A front blower motor power module is used on this model when it is equipped with the automatic temperature control (ATC) heating-A/C system (Figure
1). Models equipped with the manual temperature control (MTC) heating-A/C system use a blower motor resistor, instead of the blower motor power
module.
The front blower motor power module is mounted to the rear of the front HVAC housing, directly behind the glove box. The blower motor power
module consists of a molded plastic mounting plate with two integral connector receptacles (1). Concealed behind the mounting plate is the power
module electronic circuitry and a large finned heat sink (2). The front blower motor power module is accessed for service by removing the glove box.
