problem on the right side door pillar adjuster!

That is common problem with the mopars. The nut on back side is main problem. The hole in post is little large for room to align. If the metal around hole is good then that is OK. There should be large washer on bolt/stud outside of the hole. There is a cage on inside of post to let the nut float into position for alignment, then the cage stops rotation so bolt will tighten. Something may have broke loose there. Remove rear seat and side panel to get a look at it. Someone makes a repair kit for it. Maybe Year One. Good luck with it.
