DESCRIPTION
A blower motor power module is used on this model when it is equipped with the automatic temperature control (ATC) heating-A/C system. Models
equipped with the manual temperature control (MTC) heating-A/C system use a blower motor resistor, instead of the blower motor power module See:
Blower Motor Resistor/Description and Operation/Description.
The blower motor power module is mounted to the rear of the 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 blower motor power module is accessed for service by removing the glove box.
