Standard Motor Products RU357 HVAC Blower Motor Resistor

The Standard Motor Products RU357 is a direct-fit replacement blower motor resistor designed to restore proper HVAC fan speed control to your vehicle. The blower motor resistor regulates the electrical current supplied from the fan switch to the blower motor, enabling the fan to operate across multiple speed settings. A failed resistor typically results in the blower working only on the highest speed setting—or not at all—making this an essential repair component.
