I was trying to re-position the driver's side front door lock as it tends t o stick. I moved the latch two stops upward and it stays locked. I can't find the release mechanism, so now I can't unlock the door, nor can I fully c lose it. To make matters more interesting, the screws holding the lock mech anism in the door are so tight that my allen wrench slips or bends despite liberal doses of Wd-40. Does anyone have a suggestion?
