Standard Motor Products RU532 HVAC Blower Motor Resistor

The Standard Motor Products RU532 is a direct-fit replacement HVAC blower motor resistor designed to restore proper multi-speed fan operation to your vehicle's heating and air conditioning system. The blower motor resistor controls the electrical current flowing from the fan switch to the blower motor, enabling the selection of different fan speeds — when this component fails, the blower fan may operate only on certain speeds or stop working entirely.

Key Features:

• Direct OE replacement engineered to match original fit, form, and function
• Precision-wound resistor coils for accurate fan speed control across all settings
• High-quality ceramic construction with copper electrical connectors for reliable resistance values and improved part longevity
• Tin-plated steel terminals for maximum electrical contact and secure connector fit
• Manufactured in IATF 16949-certified facilities with TS16949 and ISO9001 quality certifications
• Sample-tested for current draw, resistance, and RPM — validated against OE specifications
• Designed to meet or exceed OEM durability standards for long, maintenance-free service life

Standard Motor Products is a trusted name in automotive electrical components, with a manufacturing and validation process that includes 48-hour load testing at all fan speeds. The RU532 is the reliable choice for restoring full HVAC blower motor functionality and passenger comfort.
