Help your cabin fan run at the speed you select with the Four Seasons HVAC Blower Motor Resistor / Switch, part number 20495, a Four Seasons switch built for the HVAC blower motor circuit. It fits many vehicles, among them the 1991-1992 BMW 318i, 1988-1991 BMW M3 and 1985-1992 BMW 318 Series, as a direct-fit replacement for the listed applications.
A blower motor resistor adds resistance to the blower motor circuit so the HVAC fan can operate at its different speed settings. This part is listed under both names, HVAC blower motor resistor and switch. Signs it may need replacing include a blower that runs only on certain speeds, only on the highest setting, or not at all. If a failed resistor is the cause, this unit replaces it. Diagnose the circuit first, because a switch, wiring or the blower motor can cause similar symptoms.
