How to Address Issues with the Front Door Latch Assembly on a Mercury Cougar?

The front door latch repair requires the user to start by disconnecting the battery ground cable. Begin by removing the door trim panel followed by delicate removal of the watershield but avoid touching its adhesive surface to prevent re-bonding failure. Before breaking the connection of both rods you must rotate the clip angle by 90 degrees. The follow-on step involves releasing the electrical cable connection followed by unhooking latch screws which enables the latch removal. To remove the cable from the latch you should turn the cable and break its connection. The reverse step should be used for installation procedures.
