2008 C220 cdi
Hi all. The car is c220 cdi. 2008. About 30 seconds after starting the engine the fan cuts in and is quite noisy. I never used to hear it at all from inside the car but do now. It runs all the time until I stop the engine then it shuts down. There are no warning lights on. The temp is just under 90 where it has always been. The aircon may be not quite as cold. Coolant level is fine. I'm not good with electrical stuff so don't know where to start. Any help much appreciated.
 
Sorted now. It was the aircon pressure switch. Had the aircon regassed and new switch fitted for about £130. Works great now.
Just had mine in -think exactly the same problem,'' suspect fault with A/C-pressure switch causing fan to stay on'' Have to wait for parts though- -the same price too £125 ;)

I bought my switch from eBay
