Hi Everyone,

I have a 1999 GS 400 w/ 150 Miles. I noticed in the last month that the engine fan stays on all the time. Meaning when I start the car in the the fan immediately starts going until I turn the car off. Has anyone experience this same problem. Is it a switch that I need to replace? Any help would be very appreciated. Thanks.

 

Check the temp switch plug or it might be the switch it self, it's bad.

 

I'll check the temp switch plug or the switch itself. Thanks!
