1 Auto Shop - Blower Motor Resistor

Changing the fan speed on your vehicles ventilation system is the job of the blower motor resistor. This simple component varies the amount of electric current that reaches the blower motor, resulting in faster or slower fan speed. Like many electrical devises, a blower motor resistor generates a lot of heat in managing current flow. As components age, resistance builds up in the system from corrosion in the wiring connectors as well as from normal wear and contamination in the motor itself. Even a clogged cabin air filter can cause excess strain on the ventilation fan. Too much resistance can lead to the resistor or the wiring harness overheating, leaving you with an inoperable fan motor and no air flow. We offer this direct replacement fix for your resistor wiring harness that has been damaged by heat. Save time and money!
