This critical component regulates the electrical current flowing between the fan speed switch and the blower motor, enabling precise multi-speed fan control for your vehicle's heating and air conditioning system.

Built to OEM-equivalent standards, the RU257 features premium copper electrical connectors that deliver more accurate resistance values for consistent, reliable performance. Standard Motor Products maintains full quality control throughout the manufacturing process—from raw componentry to finished product—ensuring each unit meets or exceeds original equipment specifications.

Key Features:

• Restores full variable blower motor speed control for heat and A/C
• Premium copper electrical connectors for precise resistance values and extended service life
• Engineered for seamless integration with the vehicle's OEM HVAC system
• Contains no remanufactured components — 100% new construction
• Undergoes extensive facility testing for correct performance across all operating conditions
• Direct OEM-style fit for straightforward installation

A failing blower motor resistor commonly causes the blower fan to operate only on certain speed settings or not at all. Replacing it with the Standard Motor Products RU257 restores full HVAC functionality and passenger comfort.
