Blower Motor Resistor: Description and Operation

Blower Motor Resistor Block:

The blower motor resistor block is located in the cowl, at the base of the windshield. There are two different blow motor resistor blocks depending on whether the vehicle is equipped with A/C or not.

The blower motor resistor block is mounted to the dash panel within the engine compartment. The resistor block 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 protective stamped steel cage. The blower motor resistor block is accessed for service by removing the cowl top screen.
