Cadillac Repair: My doors unlock when I use my brakes, and lock back when I release them., volt ohm meter, cadillac deville

Question
When I put my 1992 cadillac deville into drive or reverse, the doors unlock when I push the brake in and lock back when I release it. They also lock and unlock every time my blinker flashes. I am clueless on the solution and would really like your help.

Answer
Has there been ANY work or repairs performed on the vehicle of any kind what-so-ever prior to this problem ?.

I would say we are dealing with a ground fault. You will need to perform some simple test procedures using a DIGITAL VOLT/OHM METER where you can get most anywhere for about $15.00.
