Four Seasons HVAC Blower Motor Resistor P/N:20414
Help your heater and A/C fan run at the speed you select with the Four Seasons switch 20118, an HVAC Blower Motor Resistor that regulates the current sent to the blower motor to set fan speed. It fits many vehicles, among them the 1981-1996 Jeep Cherokee, 1986-1992 Jeep Comanche and 1981-1990 Jeep Wagoneer, as a direct-fit replacement for the listed applications. The part is cataloged under both names, HVAC Blower Motor Resistor and Switch.
In the HVAC system, the blower motor resistor sits in the circuit between the fan speed control and the blower motor. It drops voltage so the fan can run at the lower speed settings.
Signs this part may need replacing include a blower that runs on only some speed settings, or on none. If a failed resistor is the cause, this unit replaces it. Diagnose the blower circuit before replacing parts.

What does the Four Seasons 20118 blower motor resistor do?
It regulates the current sent to the HVAC blower motor so the fan can run at the lower speed settings you select from the control.
Will this Jeep Cherokee switch fit my 1981-1996 Cherokee?
Yes. The 20118 is listed as a direct-fit replacement for the 1981-1996 Jeep Cherokee. Check the Buyer's Guide tab to confirm your exact vehicle.
Does it fit other Jeep models?
Yes. It is also listed for the 1986-1992 Jeep Comanche and the 1981-1990 Jeep Wagoneer. The Buyer's Guide tab shows every listed application.
Why is it listed as both a switch and a blower motor resistor?
The part is cataloged in the switch category, while Four Seasons describes it as an HVAC blower motor resistor. You may find it under either name.
What are signs my blower motor resistor may need replacing?
A blower that works on only some speed settings, or not at all, can indicate a failed resistor. The switch, wiring or motor can cause the same symptoms, so diagnose the circuit first.
