Designed to bring back variable fan speed control, the Standard Ignition RU-233 is a Toyota Avalon blower motor resistor built as a direct-fit replacement for the 1995-1997 Toyota Avalon and the 1997-2001 Lexus ES300. Standard Ignition designed it specifically for Lexus and Toyota applications. See the Buyer's Guide tab for full application details.
As the HVAC blower motor resistor in the climate control circuit, this part changes the current sent to the blower motor so the fan can run at different speeds for the A/C and heater. If a failed resistor is the reason your fan speeds have stopped working, the RU-233 replaces it.
- Copper electrical connectors: Premium copper connectors are used for more precise resistance values, which Standard Ignition says improves resistor performance and extends part life.
- HVAC system integration: Standard Ignition's research and design process is aimed at integrating seamlessly with the vehicle's HVAC system.
- Variable speed control: Helps restore A/C and heater blower motor variable speed control, supporting HVAC performance and passenger comfort.
- Tested for performance: Undergoes extensive testing at Standard Ignition's facility for correct performance in all conditions.
Signs this part may need replacing include a blower that runs only on its highest setting, one or more fan speeds that no longer respond, or a blower that does not run at all. Switches, wiring and the blower motor itself can cause similar symptoms, so diagnose the circuit before replacing parts.
