Standard Motor Products RU393 HVAC Blower Motor Resistor

The Standard Motor Products RU-393 is a direct-fit OE replacement blower motor resistor designed to restore proper multi-speed fan operation to your vehicle's heating and air conditioning system.

This replacement resistor is engineered to return full fan speed control to your climate control system.
