Dorman Engine Cooling Fan Motor Relay 921-300 for Chrysler/Dodge — Factory-Style Connector, Durable

The Dorman 921-300 Engine Cooling Fan Motor Relay is a factory-style replacement relay designed to restore proper cooling fan control and match the original relay’s function and performance.

When a faulty fan relay causes your engine fan to run intermittently or not at all, the cooling system can overwork the engine and electrical components. The Dorman 921-300 is built with durable materials and factory-style connectors to simplify installation and deliver consistent, tested operation on the compatible Chrysler and Dodge models listed for specified years. Always verify vehicle compatibility by entering your trim into the garage tool and checking the Confirmed Fit bar before ordering.

How does this relay restore cooling fan function?
