Re: [DML] Re:Door Lock Problems

David's probably right--sounds like excessive drag on the lock mech. I've
found two places on mine:

1) If you have a two key deLorean (door key and ignition are different), the
door lock cylinders have a white nylon outer ring that is supposed to rotate
freely a few degrees around the lock cylinder body. This ring is connected
to the lock bellcrank via a wire bail; it's what mechanically moves the
bellcank when you turn the door key to the extreme right or left but allows
you to use the inside rocker and solenoid without actually turning the lock
cylinder (which of course couldn't turn if it has no key in it). Both of
mine developed so much drag over time that the lock solenoids would only
work when the car was running and the supply voltage was an extra volt or
two high. So much drag that it took a noticable extra effort to move the
rocker by hand. Silicone spray on the outside of the lock cylinder cured it
(access by removing upper inside door trim or might be able to get a spray
nozzle nearby by rolling down the window. ) Should probably be careful to
avoid spraying silicone into lock cylinder. Apparently later 1-key DeLoreans
don't have this problem.

2) The lock rod going to the front lock/latch mechanism runs behind the
lower door trim at a spot where the trim can rub it and cause extra drag.
Might need to remove the lower trim and make sure the rod is in the little
nylon guide on the inside door pull mounting bracket and not binding
anywhere.
