RE: Driver's door panel
Assuming you don't have the ES with the extra speaker above the door panel, it's pretty easy. There's about 8-9 screws - three on the bottom of the panel, 3 behind the speaker grill, 1 behind the door handle, 1 in the bottom of the door "pull" slot. After removing these, the door panel snaps out with 2-3 plastic tabs poking out. You also will then have to disconnect the various electrical connectors -- power window, power mirrors, door light, speakers, and central locking.
You will also have to disconnect the door handle rod from the interior handle, prior to setting the panel aside. Your window problem is likely the same as I experienced on my '99 Trep. The window runs inside of tracks on each side. On the bottom there are "brackets" which hold the window and are also bolted to the power window apparatus. Over time and vibration, these brackets can break off their mounts on either side causing the window to go up and down (but especially up) in strange angles or not even at all. The bracket can be found at most any mopar dealer and is fairly easy to install. Best of Luck.....Be careful carrying around that big piece of glass - it's heavier than you might think!
