Restore variable-speed control of your A/C and heater blower with the Standard Ignition HVAC Blower Motor Resistor RU-396 (also written RU396). It drops in as a direct-fit replacement for the 1997-2004 Buick Century, 1997-2004 Buick Regal, 1997-2004 Chevrolet Corvette, 1998-2002 Oldsmobile Intrigue, and 1997-2000 Pontiac Grand Prix. This resistor sets the fan-speed steps for the blower motor, so when a failed resistor is the cause of a blower stuck on one speed or working only on high, this replaces it.
- Premium copper connectors: premium copper electrical connectors help deliver more precise resistance values, improving resistor performance and offering longer part life.
- Seamless HVAC integration: the research and design process leads to seamless integration with the vehicle's HVAC system.
- Restores speed control: restores A/C and heater blower motor variable-speed control, helping to optimize HVAC performance and passenger comfort.
- GM-focused & tested: specifically designed for GM applications and put through extensive testing to help ensure correct performance in all conditions.

Frequently Asked Questions
What does this blower motor resistor do?
It sets the fan-speed steps for the HVAC blower motor, giving you variable-speed control of the A/C and heater airflow.
Which vehicles does the RU-396 fit?
It's a direct-fit replacement for the 1997-2004 Buick Century and Regal, 1997-2004 Chevrolet Corvette, 1998-2002 Oldsmobile Intrigue, and 1997-2000 Pontiac Grand Prix.
Why does my blower only work on high speed?
A failed blower motor resistor is a common cause of losing the lower fan speeds. If the resistor is the cause, this part replaces it; diagnose the cause before ordering.
What connectors does it use?
It uses premium copper electrical connectors, which help deliver more precise resistance values, improving performance and offering longer part life.
What numbers does this part interchange with?
It cross-references RU1090, JA1555, BR300, 1997091, 52470739, 52477902, 52479971, and 89019166.
