Welcome to the world of the beautiful Skyliners! Recently I adjusted the front roof locking nuts on my 57 Skyliner. Mine were too low and instead of turning down, ratcheting and moving the switch, the mechanism jammed under stress. Sometimes the y would not unlock as the motor was stalled. I was able to free them by repeatedly energizing the lock and then unlock relays. At one point I gave it a little persuasion to go up with the palm of my hand. I would say that mine were adjusted properly at one time but the weather seals on the header became hardened and would not compress enough for the locking to be completed properly. I will be installing new weatherstripping this year.

By the way when the locking mechanism is ratcheting, it makes a clicking sound.
