It fits many vehicles, among them the 2000-2011 Ford Crown Victoria, 1999-2011 Mercury Grand Marquis and 1999-2005 Lincoln Town Car, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
Four Seasons catalogs this part as a switch, and its own copy calls it an HVAC blower motor control module. It is also known as a blower motor resistor, so you may find it listed under any of these names.
- Vehicle-specific design: Made for the listed applications, with OE-style connectors.
- Precision engineered: Engineered and tested by Four Seasons, which brings more than 50 years of mobile A/C experience.
- Replacement seals: Contains the gaskets, O-rings or seals needed to properly replace the product.
Signs this part may need replacing include a blower that runs on only some speed settings, runs only on its highest setting, or does not run at all. A blower motor, control switch, fuse or wiring fault can cause the same symptoms, so diagnose the cause first. If a failed resistor or control module is the cause, the 20370 replaces it.
