Hi Diana, my name is***** of these items are controlled by way of the front signal acquisition module (SAM). It sounds like the module may have failed. It's not unusual for water to find it's way into the module and short things out. With so many unrelated symptoms a shorted module is the most likely problem. You will need to get the car to a Mercedes specialist to check and replace the module.

Let me know if you have any questions.
