2000 mitsubishi galant 4 cyl, 4 door. Rear right door had seat belt slammed in the door. Closed it properly and now when trying to open door from inside latch it won't pull the lever to unlock and open it. manual locking mechanism won't engage or disengage. Won't open from out side handle. Suggestions? Perhaps a good link to a diy fix?

there are several screws you have to remove remove the trim piece around the inside handle the panel lifts off dont pry it off or it will break the door latch usually binds and has to be replaced

On a similar problem i removed the window controll switch unit on the drivers door and cleaned the multipin socket and this solved the same and other problems i had.

Hey, You need to remove the panel otherwise u can't reattach the metal sticks that move the locks, but i think it's hard to remove it in a closed posision when u don't brake it
