passanger door stuck shut
 

i have. a 91 Laredo and since' i got it you had to flip the electric locks a couple of times before they caught to open the passenger door and the key was the same way but for the last 3 weeks it wont catch at all and its really starting to bother me does anybody have any ideas or pictures of the inside of my same door or has anyone experienced the same issue

also i have a big rust problem on my doors so all the stuff is sort of visable
