Description

Keep control of your heater and A/C fan speeds with the Four Seasons Front HVAC Blower Motor Resistor / Switch, part number 20463, the component that helps the blower motor run at its lower speed settings. It fits many vehicles, among them the 1979-1984 GMC Jimmy, 1987-1991 Chevrolet Blazer and 1991 Chevrolet V3500, as a direct-fit replacement for the listed applications.

A blower motor resistor adds resistance to the blower motor circuit so the fan can run at reduced speeds. If a failed resistor is the reason your fan works on some settings but not others, this unit replaces it. The part is listed under both names, HVAC blower motor resistor and switch.

Front position: cataloged for the front HVAC blower circuit on the listed applications.
Vehicle-specific applications: made for the vehicles shown in the Buyer's Guide.
Precision engineered: engineered and tested by Four Seasons with the aim of years of trouble-free operation.
Mobile A/C experience: backed by more than 50 years of Four Seasons mobile A/C know-how.

See the Buyer's Guide tab for the full list of vehicles.

What does a blower motor resistor do?

It adds resistance to the blower motor circuit so the heater and A/C fan can run at the lower speed settings instead of only at full speed.

What are signs the blower motor resistor may need replacing?

Signs include a fan that runs on some speed settings but not others, or does not run on the lower settings. The switch, wiring or motor can cause similar symptoms, so diagnose the cause first.

How is this blower motor resistor installed?

It is a direct-fit replacement for the listed applications. Disconnect the battery and follow the vehicle service information for the resistor's location and the removal steps.
