Rear window is stuck!!!
After parking for the day in underground parking the windows opened fine - when I raised them again there was some moisture on the windows. This morning, just as cold but windows opened fine. Your windows are probably just frozen.
As an aside, the antifreeze my car came with is horrible. froze on the windshield today and killed my visibility. Was only -10 and the stuff you buy at the gas station is good to -40. Was it Mercedes or the dealer that cheaped out to save 10 cents?
