Could be the handle, the connecting rod, or the door latch. If it opens from the outside you should be able to rule out the latch and the lock.

Try a slim jim first, down the side of the window. Or AAA or locksmith. If no luck, remove the seat first. Find the screws and bolts around the door handle and arm rest. Most Ford's have screws around the outer side of the panel. I don't believe your's does. The panel lifts or pops off. Once the panel is off, you can reach down and open the door. Just a note. I have done some to where the panel came out in pieces.

Replacing Interior Door Handle on an Oldsmobile Ciera

Since you can get the door open, half the battle is already won. Yes, open the door, pull the interior door panel and take a look around. Watch inside with a flashlight (towards the rear of the door) as you roll the window down to see if you can see what it's snagged on.
