Blower Motor Resistor for 1997-2004 Chevrolet Corvette & More - Standard Ignition RU-396

When your fan only blasts on high or quits at certain settings, the Standard Ignition HVAC Blower Motor Resistor RU-396 is the component that steps the current down to give you those in-between speeds. It drops in as a direct-fit replacement for many vehicles, among them the 1997-2004 Chevrolet Corvette, 1997-2004 Buick Century and 1997-2004 Buick Regal; see the Buyer's Guide tab for the full list.

It regulates the flow of current to the blower motor so the A/C and heater fan can operate at its variable speed settings.

• Precise resistance: Premium copper electrical connectors help deliver accurate resistance values for consistent resistor performance and longer part life.
• HVAC integration: Designed through research and development for seamless integration with the vehicle's HVAC system.
• Variable speed control: Intended to restore A/C and heater blower motor variable speed control, helping optimize HVAC performance and passenger comfort.
• GM-specific: Specifically designed for GM applications and put through extensive facility testing for correct performance in all conditions.

If a failed resistor is the cause of a fan stuck on one speed or dead low settings, this replaces it. Diagnose the cause before replacing.
