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 rear 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 - REAR/BLOWER MOTOR RESISTOR BLOCK - DESCRIPTION) .

The rear blower motor power module is installed in the back of the rear HVAC housing, directly above the A/C expansion valve. The power module consists of a molded plastic mounting plate with two integral connector receptacles. Concealed behind the mounting plate is the power module electronic circuitry and a large finned heat sink. The rear blower motor power module is accessed for service by removing the right quarter and D-pillar trim panels.
