the connections near the front axle that activate the motor to engage the system aren't melted? That's a comon problem for that body style. If there good, sounds like it could be that motor itself. To figure out if it's you motor or transfercase, jack up the rear end, have a friend inside shift into 4 wheel drive, or try to, and put it in gear and apply some gas. If the front driveshaft is turning then it's something with the front end. If not, farther back in the system.

The window should be put in a closed position.
Hidden screws behind buttons of the same color as panel should be opened up using a pick or small screwdiver.
Pry the lower part of the panel away from the door using a paint scraper, The lower half of this panel is usually held in with plastic fastners. When pulled hard enough they will release. These fastners are replacable you can buy them at your local body shop. After releasing all plastic fastners lift door panel off door lock in an upward thrust. Be careful not to pull to far away from door due to wire harnesses and speaker wires ect.. These can be uncliped to remkove whole panel. To operate window you can replug window harness wires in order to bring the window into the proper position to remove bolts that hold it into place. Carefully position glass in upward position and duct tape in place.
The regulator is held in place by three or more bolts.
Compare your new part to the existing window regulator.
Installation is reversal of removal.
Any questions get back!

Door panel is attached to door frame on the sides and bottom perimeter with push-in fasteners. There are screws that attach the arm rest/door pull to the frame , and also the panel trim around the door open/close handle.
Locate and remove all screws.
The perimeter of the panel is popped away from the door frame by inserting a flat blade screw driver between the panel and the frame.
There is a trim tool for this that works better than a screw driver. Pretty inexpensive from an auto parts store. Once the sides and bottom are free, the panel is lifted up to disengage it from the top portion of the frame where the panel is attached to the inside of the window trim.
Be careful not to pull or yank the panel too far out because of the wires that are attached to the inside of the panel.
Those plastic fasteners are replaceable, should any break when they are popped out (again, auto parts store carries these).
Hope this helps...

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
