Manage how fast your front HVAC blower spins with the Four Seasons HVAC Blower Motor Resistor / Switch 20515, a direct-fit replacement for the 2008-2010 Jeep Grand Cherokee and 2008-2010 Jeep Commander. It is listed under both names, HVAC blower motor resistor and switch, and it serves the front HVAC blower system on the listed applications. See the "Vehicles it fits" section for engine details.
A blower motor resistor sits in the blower circuit and reduces the current reaching the blower motor, which gives the system its lower fan settings. If a failed resistor is the reason your blower works on only some speeds, this Four Seasons switch replaces it.
- Vehicle-specific application: built for the listed 2008-2010 Jeep Grand Cherokee and 2008-2010 Jeep Commander applications.
- Quality contacts: designed for proper electrical conductivity.
- Precision engineered: engineered and tested by Four Seasons, which draws on more than 50 years of mobile A/C experience.
- Position: front HVAC blower system.
Signs this part may need replacing include a blower that runs on high but not on the lower settings, fan speeds that drop out, or no blower operation at all. The blower motor, the HVAC control or the wiring can cause similar symptoms, so diagnose the circuit before you replace parts.

Frequently Asked Questions
Is this a direct-fit 2008-2010 Jeep Commander switch?
It is a direct-fit replacement for the 2008-2010 Jeep Commander and the 2008-2010 Jeep Grand Cherokee. The "Vehicles it fits" section has the engine details.
What does an HVAC blower motor resistor do?
It reduces the current reaching the front HVAC blower motor so the system can provide its lower fan speeds.
Why is it listed as both a switch and a blower motor resistor?
The catalog lists it under the switch part type, and Four Seasons calls it an HVAC blower motor resistor. Both names describe this same part, 20515.
What are signs the blower motor resistor may need replacing?
Warning signs include a blower that runs only on high, missing lower fan speeds, or no blower operation. The motor or wiring can cause similar symptoms, so diagnose the circuit first.
Which part numbers does it interchange with?
It cross-references 4P1663, 68057463AA, 984486, 1712813, A06865, MT17853, SW11749C and JA1785.
