door will not lock or unlock doors, will click but will not unlock or lock
door lock on 1999 Ford F-250 Super Duty
The interior door panel will have to be removed to inspect the door lock and door lock solenoid. The fact that you hear a clicking sound when you try to operate (open or close the door lock) shows it has power getting to the lock solenoid. I replaced a door lock mechanism on my brother in laws truck, if the dealer has it in stock they probably fail. The one I put in was relatively cheap from Ford and they had two in stock..
