Blower Motor Resistors

The blower motor resistor controls the electrical current flowing from the fan switch to the blower fan, which allows motorists to set the fan at different speeds. With more than 700 blower motor resistors in the line, we offer full line coverage for domestic and import applications. To help you restore proper HVAC functions, we manufacture high-quality replacements that match the fit, form, and function of the original. On top of that, we test them to ensure performance and reliability.
