You may have to "free" the regulator from the door with a hammer. If you're careful, you won't hurt the door. If you bend the regulator, well, try to bend it back, or replace it if it breaks while you're trying to straighten it out.

That said, there are some little plastic plugs in the drain holes on the motor. Take one out of the top, and make sure the ones are in place in the bottom holes. Get some NON-FLAMMABLE electric parts cleaner, and fill that motor with the cleaner. Let it sit for a few, then pull one of the plugs out of the bottom to drain the cleaner out of the motor. Repeat this procedure at least once.

Now, pull all the little plastic plugs out of their holes and squirt some sort of LIGHT all-purpose lube into each one. Apply liberally! Let things sit for a few more minutes.

O.k. it is important before you proceed any farther that YOU HAVE A FIRE EXTINGUISHER HANDY. Don't try to roll the window down unless you have that fire bottle, right? Now, try to roll the window down. Maybe get a helper to push down on the window while you hit the switch.

If its still no-go, you can try the electric parts cleaner flush and lube thing again. Won't take long, and may save you a bunch of work.
