Standard Motor Products RU385 HVAC Blower Motor Resistor

The Standard Motor Products RU385 is a direct-fit replacement HVAC blower motor resistor engineered to restore proper fan speed control to your vehicle's heating and air conditioning system. The blower motor resistor regulates the electrical current flowing from the fan switch to the blower motor, enabling multiple fan speed settings—from low to high—to function correctly.

Built to meet or exceed OEM specifications, this resistor is manufactured from all-new components with no remanufactured parts, ensuring reliable, long-lasting performance. A failed or worn blower motor resistor commonly causes the HVAC fan to operate on only one speed or not at all, making this a critical component for restoring full climate control functionality.

Key Features:

• Direct OEM replacement — no modifications required for installation
• Manufactured from 100% new components, no remanufactured parts
• Designed to meet or exceed original equipment specifications
• Restores full multi-speed blower motor operation
• Backed by Standard Motor Products' manufacturer warranty
