Cannot open door from inside on front driverside

29 cent part my fix your problem. There is a nipple on the interior door lock lever that fits into a slot on the door handle lever. Look at passenger side to compare. The nipple is covered with a plastic spacer that may come off. The spacer keeps the lock nipple snug in the handle lever slot; pull the handle lever, it engages the lock lever, opening door. I bought a .29 cent aluminum spacer (#8x1/4 x 1/4) from Orchard hardware. Take needle nose pliers and slip the spacer on, then super glue. Unfortunately if lock lever (where riveted) is badly worn, then it may pivot upward instead of perpendicular to the door, thus defeating new spacer. But you may now be able to open door by pulling handle lever and lock lever at the same time. If you need to replace door handle, others on this site have suggested that you not replace metal frame that door handle is mounted on, but drill out rivets that hold door handle mount.

Remove the door panel because more then likely the link that goes to the door handle itself is probably broken or popped out
