Power door lock revival.
The locks were not broken. They were just old, dry, stubborn, and in desperate need of lubricant therapy.
Mission: revive the power locks.
The power locks were struggling because the latch and lock mechanisms had become stiff over the years. Removing the door panels and lubricating the mechanisms brought the system back to life.
