Slow ascend with window, no power mirrors, unplugging airbags?

You can try and lube the guide rails and surrounding rubber. Makes a mess and takes a while to clean off the glass but it usually helps. Silicone spray works well. Usually its the overengineered mass of rubber moldings that warp or come out of place and bind against the glass. The regulator itself can go bad and the cables inside can stretch. Watch the window as it moves and see if it is forcing against anything.
