My 1996 P reg inpreza 2000 drive fine with no problems but when stationery starts to overheat due to fans not cutting in at all. I have changed the sensor under manor fold, checked and changed fuses. I have also changed the radiator and fans plus thermostat and still having the same problem. Any help or advice would be much appreciated thanks

 

Have you checked for a reading out of the fan switches? Just to make sure it's not a wiring fault?

 

How about the relay????

 

could be a water pump problem or air not bleed properly in the radiator

 

connect the green connectors under the dash by your left knee when sat in the drivers seat.. the fans plus other stuff under the bonnet should pulse..

then you can check the wiring with a volt meter.. they come on ever few seconds with green connectors and ignition on.
