Description

Dial in every blower fan speed with the Four Seasons HVAC Blower Motor Resistor 20906, a Four Seasons switch that installs in the heater and A/C blower circuit across a wide range of heavy-duty trucks. It's a vehicle-specific replacement for the 1987-1990 Ford CF6000, 1981-1985 Kenworth W900, 1990-1997 Mack DM, and dozens of Peterbilt models including the 1986-1996 Peterbilt 379 and 1981-1996 Peterbilt 362 — see the Buyer's Guide tab for the full list of applications.

Quality contacts: built to promote proper conductivity through the blower speed circuit.
OE-style connectors: designed to plug into the factory harness.
Vehicle-specific application: matched to the listed trucks rather than a one-size-fits-all part.
Four Seasons backing: engineered and tested behind more than 50 years of mobile A/C experience.

The blower motor resistor sets the different fan speeds by adding resistance to the blower motor circuit, so the fan runs slower on the lower settings and full speed on high. If a failed resistor is the cause of your problem, this replaces it. A common sign it may need replacing is losing one or more lower fan speeds while high still works, or the blower not responding on certain settings.

Frequently Asked Questions

What does this Four Seasons switch do?

The HVAC blower motor resistor sets your fan speeds by adding resistance to the blower circuit, so the blower runs slower on the low settings and full speed on high.

How do I know the blower resistor may be failing?

A common sign is losing one or more lower fan speeds while high still works, or the blower not responding on certain settings. Diagnose the cause before replacing.

Does this fit my truck?

It's a vehicle-specific replacement for the listed Ford, Kenworth, Mack, and Peterbilt models. Check the Buyer's Guide tab and confirm the year, make, and model match your vehicle.

Will it plug into my factory wiring?

It's built with OE-style connectors designed to plug into the factory harness, and uses quality contacts intended to promote proper conductivity in the blower circuit.

Which vehicles does part 20906 cover?

It fits a range of heavy-duty trucks, such as the 1987-1990 Ford CF6000, 1981-1985 Kenworth W900, 1990-1997 Mack DM, and many Peterbilt models. See the Buyer's Guide for all 42 applications.
