C220 - Y/2001 ...so how many miles do I have to drive for the heater to blow hot then? I know its been a bit parky of late but 20 miles before it kicks in... surely this can't be right... checked obvious water coolant level... the passenger side just won't get hot at all.... any ideas

Your thermostat could be faulty, what temperture is showing on the gauge when warm.

There isn't an airlock in the heater matrix is there?
