Rear door on my 65 NYer will not open from outside or by pulling the door handle on inside. I made sure the lock was undone.. Should I yank the door panel off, cut a hole near the door handle on outside?
I had the same problem on my 77 NYB, we finally got it opened by having my dad push the door from the inside and me pull it from the outside. I would recommend getting the inside panel off if possible, I feel that is much better than cutting the outside of the door.
Had the same thing happen on a rear door on a 64 New Yorker. Probably have to remove rear seat and interior door panel.Maybe try to spray some PB blaster or other penetrating oil in the door jamb, aiming for the latch mechanism. That might help get things moving.
Don't cut the door.
