Four Seasons HVAC Blower Motor Resistor P/N:20181
Keep cabin airflow responding at every fan setting with the Four Seasons HVAC Blower Motor Resistor (MPN 20325), also cataloged as a Four Seasons switch. It drops in as a direct-fit replacement for the 2005-2011 Ford Crown Victoria, 2006-2007 Ford Grand Marquis, and 2005-2011 Mercury Grand Marquis — see the "Vehicles it fits" section for the full engine-level fitment. This resistor sits in the blower motor circuit and sets the resistance for each fan speed the HVAC control commands, so the motor spins slower or faster on demand.
If a failed resistor is the cause of a blower that only runs on certain speeds — or won't run on the lower settings — this replaces the original component. Diagnose the fan-speed fault before ordering to confirm the resistor is at fault.

This part cross-references / interchanges with the following part numbers:
What does this Four Seasons switch / blower motor resistor do?
It sits in the blower motor circuit and sets the resistance for each fan speed, letting the HVAC control run the blower slower or faster as commanded.
Which vehicles does MPN 20325 fit?
It is a direct-fit replacement for the 2005-2011 Ford Crown Victoria, 2006-2007 Ford Grand Marquis, and 2005-2011 Mercury Grand Marquis. Check the "Vehicles it fits" section to confirm your vehicle.
My blower only works on high — will this fix it?
A blower that runs on some speeds but not others can stem from a failed resistor, among other causes. Diagnose the circuit first; if the resistor is at fault, this replaces it.
Does it use the factory connector?
Yes. It features OE-style connectors designed to plug into the existing wiring harness.
What numbers does this part interchange with?
It cross-references 11120325, 973553, 4W7Z19A706A, 1712207, YH1717, A08195, MT1884, SW11263C, and JA1507.
