If a burned-out or corroded resistor is why your HVAC fan only runs on certain speeds, this Dorman hvac blower motor resistor kit (P/N 973-413) drops in to replace the original equipment unit. It fits a range of full-size Ford, Lincoln and Mercury sedans and wagons, including the 1992-2005 Ford Crown Victoria and 1987-1991 Ford LTD Crown Victoria — see the Buyer's Guide tab for the full list.

A blower motor resistor controls fan speed by placing resistance in the blower motor circuit; when it overheats or corrodes, some or all fan settings can stop working. This Dorman blower motor resistor kit addresses that failure when the resistor is the cause.

  • Complete kit: includes both the resistor and a harness pigtail, essential for most repairs.
  • Direct replacement: made to replace the factory resistor and harness on the listed years, makes and models.
  • Made to perform like OE: designed to help return normal HVAC fan operation when the original resistor has failed.
  • Quality-backed: supported by a team of engineers and quality specialists in the USA.

Frequently Asked Questions

What comes in the Dorman blower motor resistor kit 973-413?

Each kit includes both the resistor and a matching harness pigtail, which is essential for most repairs.

What does a blower motor resistor do?

It controls the blower fan speed by adding resistance to the motor circuit, letting the fan run at the different low and medium settings selected on the HVAC controls.

What are signs my blower motor resistor may need replacing?

Common signs include the fan working only on high, or one or more speed settings no longer working. Have the cause diagnosed, since wiring or the switch can produce similar symptoms.

Does this kit fit the 1992-2005 Ford Crown Victoria?

Yes, it is listed for the 1992-2005 Ford Crown Victoria. See the Buyer's Guide tab for the full year/make/model coverage.

Which part numbers does 973-413 replace?

It cross-references BMR037, 4P1379, RU1097, E3AZ19A706A, 20320, RU403 and JA1517.
