Am moving house today and so have a 200 mile drive to new home. But wife had to call out AA on way to old house as left hand indicator wouldnt cancel. Hazards work as does right had signal but left wont turn off. The AA (doh) didnt have any ideas. Eventually they removed the front and rear bulbs which left the interior light flashing v quick as one bulb left in (mirror). Any ideas? I can only assume it is the switch in the steering column area...? The car is 2001 E Class 320cdi estate. thanks
