Hi guys,can anyone tell me why air con fans come on around 98 and not main engine fan

they even come on regardless if heating on or off or Eco. I can simulate this by disconnecting sender block from stat. Bridge right contact+centre contact,Air con fans on. Bridge right contact+left contact main engine fan on full air con fans off. What I cant savie is why the air con fans seem to be doing the engine fans job

Or maybe i just dont know the Mig that well

. Can anyone shed some light on this

Cheers John..

Air con fans should be on low speed all the time unless ECO mode is selected or system has no gas.

First stage on the radiator switch should see the air con fans and engine fan behind the rad run at low speed.

Second stage should see the above run at full speed.

Air con fans also step up to full speed if the refrigerant pressure rises above a set value.
