Take charge of your cabin fan speeds with the Four Seasons switch 20065, an HVAC blower motor resistor that routes blower current through resistance steps so the fan motor can run at its lower speed settings. It fits many vehicles, among them the 1992-1999 Buick LeSabre, 1991-1999 Buick Park Avenue and 1992-1999 Pontiac Bonneville, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
This part is listed under two names, HVAC Blower Motor Resistor and Switch. Both refer to the same component. If a failed resistor is why your blower has lost one or more speeds, this unit replaces it.
- Precision engineered: Four Seasons builds it to be a precision-engineered part.
- Vehicle-specific applications: It is made for the listed vehicle applications.
- Quality contacts: The contacts are designed for proper electrical conductivity.
- Mobile A/C experience: Four Seasons engineers and tests its products with years of trouble-free operation as the goal. The brand draws on more than 50 years of mobile A/C experience.
Before you replace the resistor, diagnose the cause of the fan-speed problem. The blower switch, blower motor or wiring can produce similar symptoms.

Frequently Asked Questions
What does an HVAC blower motor resistor do?
It sends blower current through resistance steps so the HVAC fan motor can run at its lower speed settings instead of only at full speed.
What are signs this blower motor resistor may need replacing?
Some signs are a blower that runs on only some speeds, a blower that works only on high, or no fan on the low settings. A switch, motor or wiring fault can cause the same symptoms, so diagnose first.
Does this Four Seasons switch fit a 1992-1999 Buick LeSabre?
Yes. The 1992-1999 Buick LeSabre is a listed application. It also fits the 1991-1999 Buick Park Avenue and 1992-1999 Pontiac Bonneville. See the "Vehicles it fits" section for the rest.
Why is this part listed as a switch and a blower motor resistor?
The catalog classifies it as a Switch, and Four Seasons describes it as an HVAC Blower Motor Resistor. Both names refer to this same part, 20065.
How is this blower motor resistor installed?
It is a direct-fit replacement for the listed applications. Follow your vehicle's service information for its location and removal steps, and check the connector and wiring for heat damage.
