Greg. I had an annoying problem like you describe with my 57 Plymouth. It turned out that one of the spring catches which release the star wheel was broken. I had to replace the entire latch assembly, as these units are riveted together. I would check inside the door to make certain that the linkages are all connected and in proper adjustment first. The big dilemma with this latch mechanism is that you really cannot see the break in the spring catches. They are enclosed within the body of the latch. Hope this helps. It took me a few days to get mine figured out. George.....57 Imperial Crown Southampton, 57 Plymouth Belvedere Conv., (2) 58 Plymouth Belvedere 2 d hdtps.
