Four Seasons HVAC Blower Motor Resistor P/N:20411
This Four Seasons switch, part number 20079, is a front HVAC Blower Motor Resistor / Switch that steps down the current reaching the blower motor so the fan can run at its lower speed settings. It fits many vehicles, among them the 1983-1985 Chevrolet Impala, 1982-1983 Chevrolet Malibu and 1982-1992 Chevrolet Camaro, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The resistor sits in the blower circuit between the fan speed control and the blower motor. Common signs that it may need replacing include a fan that runs only on its highest setting or one or more speeds that no longer work. If a failed resistor is the cause, this unit replaces it. The part is listed under both names, HVAC Blower Motor Resistor and Switch.
Four Seasons engineers and tests its products and draws on more than 50 years of mobile A/C experience.
