Blower Motor Resistor: Description and Operation
Description - Front
DESCRIPTION
A blower motor resistor is used on vehicles equipped with the manual temperature control (MTC) heating-A/C system. Vehicles equipped with the
automatic temperature control (ATC) heating-A/C system use a blower motor power module, instead of the blower motor resistor.
The front blower motor resistor is mounted to the rear of the HVAC housing, directly behind the glove box. The blower motor resistor consists of a
molded plastic mounting plate (1) with an integral wire connector receptacle (2). Concealed behind the mounting plate are coiled resistor wires contained
within a ceramic heat sink (3). The front blower motor resistor is accessed for service from beneath the right side of the instrument panel.
