Description

Take charge of cabin airflow with this Four Seasons switch, the HVAC Blower Motor Resistor / Switch part number 20420. It manages the current sent to the blower motor, which helps set the fan speeds for your heater and A/C. It fits many vehicles, among them the 1991-2002 Saturn SL, 1991-2002 Saturn SL1 and 1991-2002 Saturn SL2, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list. Four Seasons lists this part under both names: HVAC blower motor resistor and switch.

OE-style connectors: built for the vehicle-specific applications it is cataloged for.
Quality contacts: designed to provide proper electrical conductivity.
Precision engineered: made for vehicle-specific applications rather than a universal fit.
Engineered and tested: Four Seasons designs it for years of trouble-free operation and backs it with more than 50 years of mobile A/C experience.

A blower motor resistor may need replacing if the blower runs on only some settings (often just the highest) or no longer changes speed. A faulty blower motor, control switch or wiring can cause similar symptoms, so diagnose the cause before replacing. If the original resistor / switch is the cause, this unit replaces it.
