    you may have a refrigerant issue and it has leaked out or
    there is a control issue and the compressor is not coming on or the heat is on at the same time as the a/c. this system is not easy to diagnose, especially if you don't have a scanner with MB software or a/c gauges. suggest looking for a local MB specialist who has the proper tools
    and knowledge to diagnose this problem.

    I absolutely agree with Overbys. You need a good MB shop to diagnose the problem.
