Roll up windows manually? on 1990 BMW 325i

I have a 87 BMW and the rear passenger window won't roll up, it's only down about 3 inches. Is there anyway to get it up? I don't need it to roll down again, I just need the window up, and am not really interested in replacing the regulator or the motor. Thanks

swap switch from other window and see if it goes up
If operating the switch and pulling up doesn't provide a solution, the door trim is to be removed and the situation assessed. At that point you can remove this and that and jam the window up with something
