Grand Caravan V6-3.3L Flex Fuel (2008)
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.
