Hi,

I have a C240 2001, the fan works fine, until the engine reach its normal temp (less than a 100 C), but after sometime, the fan enters in high speed and after a couple of seconds (less than 15 seconds), it shuts down and stop working, and i need to stop the car, stop the engine and start it again so the fan can work again.

But if i keep the AC on after this, it starts doing the same over and over (normal -> High speed -> Shutsdown). I was told it could be the temp sensors in the car, or the AC pressure sensor of the AC cause it only happened with the AC on.

Any help would be greatly appreciated.

Thanks.
