Sounds like you may be having failures with you front SAM module. You have a front and rear sam. They basically control interior functions for your front and rear components. As they begin to fail you will have intermittent faults that appear to have no ryhme or reason to the failures, i.E. Unrelated components intermittently failing. As this is a computer module it will need to be properly diagnosed by a MB tech. I would recommend using a dealer as the STAR diagnostic system they use will be the most accurate way to diagnose this problem.
