Standard Motor Products RU617 HVAC Blower Motor Resistor

The Standard Motor Products RU617 is a direct-fit HVAC blower motor resistor engineered to restore proper fan speed control to your vehicle's heating and air conditioning system. This resistor regulates the voltage supplied to the blower motor, allowing the blower fan to operate at multiple speed settings as selected by the driver.

A faulty blower motor resistor is one of the most common causes of a blower fan that only works on one speed (typically high) or stops working altogether. Replacing the resistor with a quality OE-equivalent unit like the RU617 restores full multi-speed functionality without the need for costly dealership repairs.

Key Features:

• Direct OE replacement — designed to match original equipment form, fit, and function
• Engineered to Standard Motor Products' strict quality control standards
• Restores proper multi-speed blower fan operation
• Constructed with high-quality resistive wire and thermal protection components
• Designed for straightforward, plug-and-play installation
• Helps resolve blower motor operating on high speed only, or not operating at all

Standard Motor Products has been a trusted manufacturer of ignition, electrical, and temperature control components for over 100 years. The RU617 is built to deliver reliable, long-lasting performance as a true OE-quality replacement part.
