Cadillac Repair: 93 seda deville - door locks dont work, volt ohm meter, rear doors

Question
Problem: Entry lights on rear doors stay on when all doors closed and turn off when any door is open. AND Electric door locks failed at the same time the light problem happened.

I have replaced the fuse for the rear entry lights and door locks under the dash. It will work for a short time until passenger side door is slammed. Then it shorts again. After new fuse, all worked, then shorted again when I pushed the door jam "pin" by hand in. Could the pin be the problem? If not, any suggestions? Thanks!
