Manage your cab's heater and A/C fan speeds with the Four Seasons HVAC Blower Motor Resistor / Switch 20342, a direct-fit replacement for the 2000-2006 Toyota Tundra. It is a vehicle-specific part with OE-style connectors, and it is listed under both names, blower motor resistor and switch.
In the HVAC system, the blower motor resistor sets the lower fan speeds by limiting the current that reaches the blower motor. If a failed resistor is why the fan works on some settings but not others, this unit replaces it.
- Quality contacts: designed to provide proper conductivity.
- Vehicle-specific application: built for the 2000-2006 Toyota Tundra.
- OE-style connectors: styled after the factory connections.
- Engineered and tested: Four Seasons designs and tests its parts with trouble-free operation as the goal, drawing on more than 50 years of mobile A/C experience.
Signs this part may need replacing include a blower that runs only on its highest setting, one or more fan speeds that stop working, or no airflow at the lower settings. Wiring, control switch and blower motor faults can cause similar symptoms, so diagnose the cause before replacing. See the "Vehicles it fits" section for engine-level fitment details.

Frequently Asked Questions
What does a blower motor resistor do?
It limits the current reaching the HVAC blower motor so the fan can run at its lower speed settings.
Why is this switch listed as a blower motor resistor?
The part is known by both names. Four Seasons describes 20342 as an HVAC blower motor resistor, and it is also cataloged under the switch category.
Will it fit my 2000-2006 Toyota Tundra?
Yes, it is a direct-fit replacement for the 2000-2006 Toyota Tundra. Check the "Vehicles it fits" section for full application details.
What are the signs of a failing blower motor resistor?
Signs it may need replacing include a fan that works only on high, missing speed settings, or no airflow on lower speeds. Wiring, switch or motor faults can cause similar symptoms, so diagnose first.
What features does the Four Seasons 20342 have?
It has quality contacts designed for proper conductivity, OE-style connectors and a vehicle-specific design. Four Seasons backs it with more than 50 years of mobile A/C experience.
