Our new to us 2002 E320 4-matic wagon had a strange problem today. My wife stopped at the drive in ATM machine and could not reach the machine so she opened the door. When she drove off the power window would not work nor would the turn signals. After arriving home and restarting the car everything was back to normal. Any ideas what caused this?

 

repeat it,if you can.might just be a glitch or might be a combination of what she did and the alarm system not liking someone opening the door with the car running.
post what you find,it will be of help to someone in the future or searching in the past.

sounds like a short circuit to me
