2002 Ford Taurus automatic door locks disengage themselves

The automatic door locks disengage themselves within 2 seconds. I switched them over to manual using a procedure found on the internet. It’s getting worse. Now the door locks can only be engaged with the key out and the drivers side door won’t turn on the interior lights. Sounds like faulty wiring passing through the door jamb to the body. Is this a major problem trying to locate and repair wiring from the door to the body?

It’s not a major problem, but it is time consuming, laborious, and not fun
