Blower Motor Power Module: Description

WARNING: This page is about a different car, the 2005 Dodge Grand Caravan, 2005 Dodge Caravan, and 2005 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

A front blower motor power module is used on this model when it is equipped with the automatic temperature control (ATC) heating-A/C system. See Fig 1. Models equipped with the manual temperature control (MTC) heating-A/C system use a blower motor resistor, instead of the blower motor power module (Refer to HEATING & AIR CONDITIONING/CONTROLS-FRONT/RESISTOR-BLOWER MOTOR - DESCRIPTION) .

The front blower motor power module is mounted to the rear of the front HVAC housing, directly behind the glove box. The blower motor power module consists of a molded plastic mounting plate with two integral connector receptacles (1). Concealed behind the mounting plate is the power module electronic circuitry and a large finned heat sink (2). The front blower motor power module is accessed for service by removing the glove box.
