I have a '99 E320. Today I lowered all the windows down about half way to cool off the car before getting in. I opened and then shut the back door (with the windows still half-way down) to put something in the back. When I then started the car, I pressed the switch to raise the windows. When the back window (on the door I had previously opened and closed) reached the top I heard a loud pop (almost like a gunshot) and then found that the window must have broken within the door as it now slid down and could not be raised. Seems quite odd - has this happened to others or could my closing the door with the window half-way opened somehow put the glass out-of-synch with the door guides?
Thanks.
