I am new to the Mercedes and hoped I would not have to address a problem as my first post. But...........now here I am. We just had a freak rain storm here in AZ and all of the sudden none of the switches on the driver's door worked. None of the window switches, trunk release, nor the seat switches. When the car had an opportunity to dry out everything works right as rain. Any ideas would be appreciated.

PS I searched with no luck already
