Four Seasons 37827 switch for the 2001-2005 Toyota RAV4 and other vehicles is a radiator-mounted temperature switch for the engine cooling fan. This Four Seasons switch senses temperature at the radiator for the fan circuit.
- Engineered and tested for years of trouble free operation, backed by over 50 years of mobile A/C experience
- Vehicle specific applications
- Brass construction for accurate temperature sensing
- Zinc coated terminal to resist corrosion
A cooling fan that does not come on, or an engine that runs hot, can mean the switch is failing. Before you replace it, look at the switch and its terminal with the engine off and cool for cracks, corrosion or coolant seepage, because a fan or wiring fault can look the same from the driver's seat.
It also fits the 2000-2005 Toyota Echo and the 2001-2005 Lexus IS300. If your car is not named here, look up its year, make and model in the "Vehicles it fits" section.
