It's snowing hard and I'm screwed!

10 minutes ago I left the office to get lunch. It has snowed 8 inches since I parked this morning with more on the way. I'm driving along and all off a sudden my rear driver side window decides to go down -- all by itself and it won't go back up. I have 50 miles to drive in a snow storm, departing in about 90 minutes. Can anyone offer some advice on how to get the frickin' window up? I'd be grateful...... 1994 Grand Cherokee 5.2L

Duct tape a plastic bag (30 gal trash size) over the window. That should get you home.
Sounds like a short happened, and it rolled down the window and is stuck in a open down loop, you could try removing the fuse to the window switches and see if this helps, but Im kind of doubting it.

Goodluck
