DESCRIPTION

Both the Automatic Temperature Control (ATC) and Manual Temperature Control (MTC) heating and A/C systems use a blower motor power module to control blower motor speed.

The blower motor power module is mounted to the bottom of the HVAC housing, on the passenger side of the vehicle. The blower motor power module consists of a molded plastic mounting plate (1) with an integral connector receptacle (2). Concealed behind the mounting plate is the power module electronic circuitry (3) and a finned aluminum heat sink (4).

The blower motor power module is accessed for service from under the instrument panel.
