Auxiliary Fan

[seb]

Silly question probably...Auxiliary cooling fan, the one you can see though the front grill behind the front bumper..... What exactly does it do? When will it switch on? Is it dedicated for the AC system?

If u on your aircon it will run at low speed, if engine tempertaure gets too hot (99deg C), fan will run at high speed. If aircon off fan off and waits to run high speed if engine temperature goes over 99deg C.

Thanks ersalle. Hmm... That's what I thought. I think it's faulty. It is not turning when my AC is on. That could be the cause of the dodgy AC issue I posted earlier.

Check the fuse 1st to see if it is ok before jumping into conclusion, good luck!!

simple resistor can cause fan stop working.Try direct feed (high speed)

Problem solved. It was a blown fuse :blush: and the fact that the cooling fan was working the compressor was working overtime to keep to the set temperature.
