Standard Motor Products RU287 HVAC Blower Motor Resistor

The Standard Motor Products RU287 is a direct-fit replacement HVAC blower motor resistor engineered to restore proper heating and air conditioning fan speed control to your vehicle. The blower motor resistor regulates the electrical current flowing from the fan switch to the blower motor, enabling multiple fan speed settings — from low to high.

Standard Motor Products designs this resistor to match the original equipment fit, form, and function, ensuring a straightforward, no-hassle installation. Built to meet or exceed OEM specifications, it delivers dependable, maintenance-free operation so you can count on reliable climate control performance.

Key Features:

• Direct-fit replacement restores A/C and heater blower motor variable speed control
• Constructed from high-quality ceramics with copper electrical connectors for accurate, precise resistance values
• Tin-plated steel terminals for maximum contact and excellent electrical connectivity
• Engineered to meet or exceed original equipment specifications for long service life
• Manufactured in an IATF 16949 and ISO 9001 certified facility
• Sample-tested for draw, resistance, and RPM; validated to OE specs and subjected to 48-hour load testing

A failed blower motor resistor commonly causes the fan to operate only at certain speeds or not at all. Replacing it with the Standard Motor Products RU287 restores full multi-speed HVAC fan operation and eliminates one of the most common causes of heating and cooling system complaints.
