Manage the rear blower's fan speeds with the Four Seasons HVAC Blower Motor Resistor / Switch 20309, a direct-fit replacement for the 2007 Ford Expedition, 1999-2003 Ford Windstar and 2007 Lincoln Navigator. This rear-position unit sits in the rear blower motor circuit and varies the current reaching the motor, which gives the fan its different speed settings. Four Seasons describes it as an HVAC Blower Motor Resistor, and it is also cataloged under the Switch category. Both names refer to this part. Engine details for each vehicle are in the Buyer's Guide tab.
- Vehicle-specific: built for the listed applications.
- Precision engineered: precision engineering for vehicle-specific fit.
- Quality contacts: designed to provide proper electrical conductivity.
- OE-style connectors: connectors in the style of the original equipment.
This Four Seasons switch is engineered and tested for trouble-free operation. It is backed by the brand's more than 50 years of mobile A/C experience.
Signs this part may need replacing include a rear blower that runs on only some speed settings, runs only on high, or does not run at all. Wiring, the blower motor or the controls can cause similar symptoms, so diagnose the cause before replacing any part.
