Built to regulate the heater and A/C fan speeds in your cab, the Standard Ignition Toyota Tundra blower motor resistor, part number RU-412, is a direct-fit replacement for the 2000-2006 Toyota Tundra and is specifically designed for Toyota applications. See the Buyer's Guide tab for engine details.
The resistor sits in the blower motor circuit and controls the current sent to the motor, which sets the fan speed you select.
- Copper electrical connectors: Used for more precise resistance values, improving resistor performance and offering longer part life.
- HVAC integration: Its research and design process is aimed at seamless integration with the vehicle's HVAC system.
- Variable speed control: Designed to return variable-speed control to the A/C and heater blower motor, helping optimize HVAC performance and passenger comfort.
- Tested: Undergoes extensive testing at the manufacturer's facility to verify correct performance in all conditions.
Signs a Tundra blower motor resistor may need replacing include a fan that runs only on its highest setting, one or more speeds that no longer work, or a blower that will not run on the lower settings. A failed switch, motor, connector, or wiring can cause similar symptoms, so diagnose the circuit first. If the HVAC blower motor resistor is the cause, RU-412 replaces it.
