Blower Motor Resistor: 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 blower motor resistor is used on vehicles equipped with the front manual temperature control (MTC) heating-A/C system. See Fig 1. Vehicles equipped with the automatic temperature control (ATC) heating-A/C system use a blower motor power module, instead of the blower motor resistor (Refer to HEATING & AIR CONDITIONING/CONTROLS - FRONT/BLOWER MOTOR POWER MODULE - DESCRIPTION) .

The front blower motor resistor is mounted to the rear of the front HVAC housing, directly behind the glove box. The front blower motor resistor consists of a molded plastic mounting plate with an integral wire connector receptacle. Concealed behind the mounting plate are coiled resistor wires contained within a ceramic heat sink.

The front blower motor resistor is accessed for service by removing the glove box.
