Standard Motor Products RU479 HVAC Blower Motor Resistor

The Standard Motor Products RU479 is a direct-fit replacement blower motor resistor designed to restore variable speed control to your vehicle's heating and air conditioning system. This electrically operated resistor controls the electrical current flowing from the fan switch to the blower motor, allowing you to adjust fan speeds for optimal comfort.

Key Features:

• Direct-fit OE replacement restores HVAC blower motor variable speed control
• Manufactured with high-quality ceramic materials and copper electrical connectors for precise resistance values
• Tin-plated steel terminals ensure maximum electrical contact and reliable performance
• Engineered to withstand high electrical current that can damage inferior resistors
• Manufactured in IATF 16949-certified North American facilities to meet or exceed OE specifications
• Rigorously tested for current draw, resistance, and RPM performance at all fan speeds

Standard Motor Products blower motor resistors undergo comprehensive 48-hour load testing and thermal cycling validation to ensure long service life under all operating conditions. Each resistor is precision-engineered to match the fit, form, and function of the original equipment component.
