The heater fan in my ML280 is running (pretty fast) when I switch the ignition off. It starts after about 5-10 seconds after the ignition is switched off, and keeps running. If I press the parking heated switch it then slows to what would be normal. Any thoughts?
 
Solved:
Found corrosion on the fan PCB between the control wire contacts and the aluminium back plate. Cleaned this carefully and normal service was restored. Not sure how the water is getting in to create the corrosion, but seems like a common problem.
