Four Seasons HVAC Blower Motor Resistor P/N:20505
$34.99

Restore working fan speeds to your climate control with the Four Seasons HVAC Blower Motor Resistor 20505. It installs as a direct-fit replacement for the 1997-2002 Ford Expedition, 1995-2001 Ford Explorer, 2001-2003 Ford Explorer Sport, 2001-2005 Ford Explorer Sport Trac, and 2002-2003 Lincoln Blackwood (see the Buyer's Guide tab for engine-level details). The resistor sits in the blower circuit and steps down voltage to set the lower and intermediate fan speeds; when it fails, the blower commonly runs only on high or drops certain speeds entirely. If a failed resistor is the cause, this part replaces it.

  • Precision engineered: built and tested for years of trouble-free operation, backed by over 50 years of Four Seasons mobile A/C experience.
  • Vehicle-specific application: matched to the listed Ford and Lincoln models.
  • OE-style connectors: designed to plug into the factory harness.

Diagnose the cause of the fan-speed issue before replacing, as wiring, the blower motor, or the switch can produce similar symptoms.

Frequently Asked Questions

What does this blower motor resistor do?

It sits in the blower circuit and steps down voltage to control the lower and intermediate fan speeds of the HVAC system.

What are signs this resistor may need replacing?

A common sign is the blower working only on high while the lower speeds are dead, or certain fan speeds not functioning. Diagnose the cause before replacing.
