Yesterday I washed my 2007 SL 550. No high pressure water was used, just a gentle flow from a nozzle that makes a gentle spray on my hose. After finishing everything was OK. This morning when I went out the rear window on the passenger side was down. I cycled the top and the rear window came back up. Could this have been caused by water getting in the rear window when I washed the car?

You might want to pull the panel in front of the right rear cubby and see if you have any moisture around the rear fuse block. Your roof module sits under that and it is what controls the rear windows.
