If a failed resistor has left your fan blowing on only one setting or skipping speeds, the Standard Ignition RU-451 blower motor resistor for the 1990-1993 Acura Integra is designed to bring back variable blower speed control. It is a direct-fit replacement for the 1990-1993 Acura Integra. See the Buyer's Guide tab for engine details.
A blower motor resistor sets the fan speeds you pick on the heater and A/C controls. It does this by varying the resistance in the blower motor circuit. If the original resistor has failed and is causing lost fan speeds, this unit replaces it.
- Copper electrical connectors: Premium copper connectors are used for more precise resistance values. They are intended to improve resistor performance and offer a longer part life.
- HVAC system integration: The research and design process is aimed at seamless integration with the vehicle's HVAC system.
- Variable speed control: Designed to restore A/C and heater blower motor variable speed control, helping optimize HVAC performance and passenger comfort.
- Acura-specific and tested: Specifically designed for Acura applications. It goes through extensive testing at the manufacturer's facility, intended to confirm correct performance across conditions.
Signs this HVAC blower motor resistor may need replacing include:
- a blower that runs only on the highest setting
- one or more missing fan speeds
- no airflow on certain settings
A switch, wiring, connector or the blower motor itself can cause similar symptoms, so diagnose the cause before replacing.
