Some Cadillac DeVille owners report experiencing issues with their electric locks, particularly with the driver's door failing to unlock. This malfunction may stem from a faulty or damaged locking system, which can prevent the door from operating correctly. Additionally, some owners have identified a bad splice in the door sill area as a potential cause, leading to a situation where the doors lock but do not unlock. Another reported issue involves the incorrect attachment of the outside handle rod to the latch, known as "preload," which can hinder unlocking via the key fob, electrical switch, inside lock knob, or key cylinder. Diagnosing the specific cause of these issues is crucial for restoring proper functionality to the driver's door electric lock.
