Front Blower Motor Power Module - Description

DESCRIPTION

NOTE:
Automatic Temperature Control (ATC) shown. Manual Temperature Control (MTC) similar.





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

The front blower motor power module is mounted to the HVAC housing, on the passenger side of the vehicle. The blower motor power module consists of a molded plastic mounting plate (1) with two integral wire connector receptacles (3). 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 from underneath the instrument panel.
