Regain control of your fan speeds with the Standard Ignition HVAC Blower Motor Resistor RU-271, a direct-fit replacement that drops into the 1990-1991 Dodge Colt, 1989-1991 Eagle Summit, 1994-1998 Mitsubishi Galant, 1989-1992 Mitsubishi Mirage, and 1990-1991 Plymouth Colt. The blower motor resistor sets the resistance in the blower circuit to deliver the different fan speeds you select; if a failed resistor is the cause of missing low/medium speeds or a blower stuck on high, this part replaces it.
- Premium copper connectors: help provide more precise resistance values for improved resistor performance and longer part life.
- Variable speed control: designed to restore A/C and heater blower motor variable speed operation, helping optimize HVAC performance and passenger comfort.
- Application-matched: specifically designed for Dodge and Mitsubishi applications, with a design process aimed at seamless integration with the vehicle's HVAC system.
- Tested: undergoes extensive testing at the facility to help ensure correct performance across conditions.
