Control how fast your heater and A/C fan blows with the Four Seasons switch sold as the HVAC Blower Motor Resistor / Switch, part number 20254. It fits many vehicles, among them the 1994-1996 Chevrolet Impala, 1991-1996 Chevrolet Caprice and 1991-1994 Chevrolet Commercial Chassis, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
A blower motor resistor sits in the blower circuit and lowers the voltage sent to the fan motor, which lets the HVAC control select different fan speeds. If a failed resistor is why your blower runs on only some settings or not at all, this unit replaces it. The part is listed under both names, HVAC Blower Motor Resistor and Switch.
- Vehicle-specific applications: built for the listed vehicles, not as a universal part.
