Standard Motor Products RU45 HVAC Blower Motor Resistor

The Standard Motor Products RU45 is a direct-fit replacement blower motor resistor designed to restore variable speed control to your vehicle's heating and air conditioning system. This critical HVAC component controls the electrical current flowing from the fan switch to the blower motor, allowing you to adjust fan speeds for optimal climate control and passenger comfort.

Key Features:

• Premium copper electrical connectors ensure accurate resistance values for reliable performance and extended service life
• High-quality ceramic construction withstands extreme temperatures and high current loads
• Tin-plated steel terminals provide maximum electrical contact and ensure proper fit and function
• Direct-fit replacement design integrates seamlessly with OE HVAC systems
• Manufactured in IATF 16949-certified facilities with rigorous quality control standards
• Sample-tested for current draw, resistance, and RPM to meet or exceed OE specifications

Standard Motor Products blower motor resistors undergo extensive testing including 48-hour load tests and performance validation at all fan speeds to ensure reliable operation under all conditions. When your blower motor only operates on high speed, a failed resistor is typically the cause, and the RU45 provides a proven OE-quality solution.
