Does anyboby know where the relay switch is located on the 1998 Lexus ES300? My cooling fans does not turn off automatically anymore, and the technician suspected the relay switch is faulty and must be replaced. Do you guys agree? But when I start the engine, the fan stops running, but right after I turn-off the engine, the fans then starts to run again for hours, and would not stop. Any suggestions, will be highly appreciated. Thanks a lot.
