    Got the same problem too on a 2007 E270 CDI: heater quit working, fan blows only cold air. Looks like A/C is not working either. Does any one know the solution to this problem please?

Heater blows cold front and back

You could be low on coolant - better check.

Your heater core might be the problem:

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...

first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

Have you checked the coolant level? If it's low, it will result in diminished heat, and could be the problem.

Heater doesn't blow hot air

First check the coolant level in the radiator. Check your heater core hoses on the firewall underneath the hood. Let the car come up to temp. and feel the two hoses. If only one of them is getting hot you may have bad heater core or a bad heater control valve.
