A temporary condition may exist on some of the above models as a result of washing the vehicles in extremely cold weather (near or below 0° F) whereby it could be difficult to unlock the front doors; or if opened and equipped with electric door locks, it may be difficult to latch beyond the secondary latch position.
If experienced, the following procedure applied to the door lock system (after opening and thawing) should prevent recurrence of the subject condition.
