Control Module HVAC: Description and Operation
Front Blower Motor Power Module - Description
DESCRIPTION
A blower motor power module is used on this model when 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 block, instead of the blower motor power module .
The front blower motor power module is mounted to the rear 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 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.
