Review on Four Seasons 37506 Relay by Keith Wolff

Perfect Fit, just make sure you are troubleshooting properly, before replacing this module, check the 8 wires that supplied with the module, make sure that the harness connectors are not burned and check the integrity of the cables. From the beginning it was believed that these modules would last several years and then need to be replaced, not forever. Last bought about ten years ago at a major dealership for $20 (original TRW), now they are about $80 at the same store and must be ordered. I got the Revain for $23 (Four Seasons made in Canada). To check if the module is working, disconnect the wire from the engine temperature sensor and ground it, the electric fan should spin.
