If it will not unlatch from the top, you can remove "door jam" piece that the door locks on and attaches to the cab. You will have to remove the trim piece that covers it. This will allow you to open the door. If it will not unlatch from the bottom, no such luck. But you can get the door panel off without opening the door. I had to get into the back and work on my knees. Now if both doors are closed, then I guess you will have to climb over the seat. When you get the panel off, pull on the cable in several different directions until you get it to release. Good luck.
