Module, Power, Blower Motor: Description
Automatic Temperature Control (ATC) shown in the illustration. Manual Temperature Control (MTC) similar.
Both the Automatic Temperature Control (ATC) and Manual Temperature Control (MTC) heating and A/C systems use a blower motor power module to control the blower motor speed.
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 housing with integral wire connector receptacles (1) and mounting provisions. Concealed behind the housing is the power module electronic circuitry and a finned aluminum heat sink (2). The blower motor power module is located on the passenger side of the HVAC housing and is serviceable without removal of the HVAC housing.
The blower motor power module is accessed for service by removing the glove box.
