Standard Motor Products RU-726 HVAC Blower Motor Resistor

The Standard Motor Products RU-726 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 speed switch to the blower motor, enabling the selection of multiple fan speeds — from low to high.

Built to meet or exceed original equipment specifications, this resistor is manufactured from new components with no remanufactured parts, ensuring consistent and reliable performance across all operating conditions.

Key Features:

• Controls electrical current to the blower motor for multi-speed fan operation
• Manufactured from all-new components — no remanufactured parts
• Designed to meet or exceed OEM specifications
• Direct plug-and-play fitment for straightforward installation
• Engineered for reliable performance in both city and highway driving conditions
• Backed by Standard Motor Products manufacturer warranty

A failing blower motor resistor commonly causes the HVAC fan to operate only at certain speeds or not at all. Replacing the RU-726 restores full functionality to your climate control system and is a straightforward DIY repair on most applications.
