Resistor-Blower Motor: Description
WARNING: This page is about a different car, the 2007 Jeep Grand Cherokee. 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 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. See DESCRIPTION .
The 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 blower motor resistor is accessed for service by removing the glove box.
