Dorman OE Solutions Engine Cooling Fan Motor Relay. The typical electric cooling fan circuit includes a temperature sensor, a relay, a control module and the fan motor. The relay is the component that fails most often, so be sure to test the relay as well as its power supply and ground connections.
A good relay coil will typically read 40 to 80 ohms. If resistance is high, the coil may still be working but it is failing, or it may not work when electrical loads are high. If the coil has no resistance, it is open and has failed. Replace the relay.
Designed to fit and install like the original, Dorman OE Solution products specifically cover those original parts with high failure rates. Many of Dorman OE Solutions products are new-to-the-aftermarket, offering the service dealer a better alternative to the OE Dealer. These parts have been re-engineered to be better than their original OE design.
