Buddy Burns Posted May 18, 2011 Share Posted May 18, 2011 I hard wired the fans to the battery and they worked fine. I replaced the sensor at the bottom of the radiator(i was told this was the switch that turned the fans on) and the fans still don't work. the car keeps overheating, the water pump works, new radiator, new thermostat. Coolant is running through the whole system but the fans won't come on. Is this why my car keeps overheating? Why won't the fans come on? I have a 98 gs400, any advice would be greatly appreciated thank you Quote Link to comment Share on other sites More sharing options...
Raisedalloy Posted May 22, 2011 Share Posted May 22, 2011 I thought I had the same problem too. Does the dashboard read at a higher temp? I notice that the fans come on when you turn on the A/C. Try doing that. Quote Link to comment Share on other sites More sharing options...
