door problem on 1990 GMC 1500 Pickup
It sounds like the drivers door on your 1990 GMC 1500 Pickup is sagging. Check the door alignment just as the door is against the striker (bolt). The door should be perfectly aligned at that point. If it is low then most likely the hinges or hinge pins are worn.
