Hi to all members,

Here comes my problem:
My recently bought 1994 C180 (1,8 liter M111) is equipped with manual air conditioning sysytem (Euro style one with dial knobs). And after cold-starting in morning the light on the "EC" button comes on (fan selector at "0" position) and stays on unless i manually turn it of. If i turn it off manually it turns itself on again after 4-5 seconds and i can hear the vacuum pump running in the trunk together with a vacuum element "squeaking" behind the glovebox. This wierd behaviour of the system continiues for 10 - 15 minutes. Then everything returns to normal ("EC" light goes out and only comes on when fan selector is set at least "1", Cooled and heated air available from all ducts/vents)

I know that if "EC" light is lit constantly, it indicates a low refigerant level but my A/C blows cold enough for me and rest of the system operates normally after first 10 - 15 minutes of driving.

I will apriciate all comments on the problem because it is starting to make me angry over the time and i do not want the local stealership touch my car before i have i clue about what is going on.

Thanks in advance
Umut
