Passenger side door opens about 6 inches and stops. Push it further and it will continue to open. When it closes it stops at the same point, about 6 inches short. Push it to close and it will finish closing.

Clean and lubricate the door rails with white Lithium "lubriplate" grease.

hinge is broke

This may be as simple as relearning the window stop positions. Perform the following procedure to relearn the windows;

1) Sit in the drivers seat and ensure both doors are fully closed.
2) Turn the key to the ON position but do not start the vehicle.
3) Pull up on the drivers window switch until the window reaches the full up position, then CONTINUE HOLDING THE SWITCH UP for 2-5 seconds, then release the switch.
4) Push down on the drivers window switch until the window fully opens, then CONTINUE HOLDING THE SWITCH DOWN for 2-5 seconds, then release the switch.
5) Repeat steps 1-4 for the passenger window.
6) Close both windows and check the operation of the smart glass.

Check the wiring harness for the door cable. 2004, 05, and 06s had the same issues. Over time, the dorr may catch the cable in the track, giving a slight yank, or moisture gets into the harness fouling the conection.

check the tracks that it rides in and if clear it may need some lube!

latch is stuck with door handle in open position , move latch tumbler (looks like crab claw) on side of door ,it will be in closed position to open position. may require some force to open ,but the latch is the problem, will have to have a new one installed.

I had a similar problem with a '95 Olds. Turned out that the wires between the door frame and the driver's side door had broken from the constant flexing of the door opening and closing.

Same problem on passenger door 92,000 miles. Dealer said he can reset the regulator inside the door by pressing button. I am looking for more information on this problem too. He estimates 1/2 hr (~$50) to do work.

My 97 Grand Prix sunroof tracks are offset. My driver side track is in the closed position, and the passenger side track is in a half open position. When the problem happened I was closing the roof and heard a hard clicking. It stopped working from that moment on. The tracks werent offset as much as they are now before I took the glass off. When I removed the glass, the passenger side track sprung back about 6 inches. The motor works, but the tracks only move about a half inch forward and backwards. Its cable operated and my guess is that one side jumped the track or a gear or something. Anybody help?

If it stops in roughly the same spot every time, and won't respond after it has stopped, it sounds like a broken wire. It is likely losing its electrical current to run the motor. It should be right where the track bends when the door has stopped. Check for loose or frayed wiring inside the flexible plastic track just below the door. The wires will often wear after being bent over and over again. If you find a broken bit of wire, cut out that section and splice in a new length of wire. Be sure you do a good job splicing, or you may end up with the same issue again soon. I am not a mechanic by any means, this just makes sense to me, and I'm considering buying an 01 town and country with this issue, which is why I'm on this site to begin with. Best of luck -
