Good Afternoon,

I am currently having trouble with my E240. The A/C fan won't stop even when I stop the engine and take the key out the ignition. So far the only way I have managed to get it to turn off is by disconnecting the battery. The speed dial on the dash for the fan does not respond and this just started happening out of the blue. I have also taken out the relevant fuses and again nothing.

Any suggestions greatly appreciated.
