What to Do When the Left Rear Car Door Won't Open?

[OGeorge]

If the door cannot be opened from either inside or outside, it is likely that the internal lock mechanism is faulty. Replacing it with a new one should solve the issue, or if the return spring on the lock mechanism has fallen off, removing the door panel and reinstalling the spring will fix it. If the door cannot be opened from the inside, it is probably due to the child lock. First, open the door from the outside, then locate the child lock switch on the side of the door and set it to the off position. Solutions for a rear door that won't open: 1. Child Lock: Check if the child lock is properly deactivated. 2. Handle Force: Examine whether the interior handle is functioning normally. If pulling the interior handle feels unusually easy, as if there is no resistance, the handle may be broken, or the linkage between the handle and the lock mechanism may have detached. If the handle feels normal but the door still won't open, the linkage may have stretched (possibly caused by someone unfamiliar with the car forcefully pulling the handle while the central locking was engaged). This can be adjusted. 3. Handle Bracket: If neither of the above issues is present, inspect whether the bracket connecting the interior handle to the lock mechanism is broken.
