for awhile now if my caar sits for more than a day i need to jump it because something is draining the battery. The electric door locks, trunk and the lights never shut off so I had to take out most of the light bulbs and now the car needs to be jumped everytime I turn off the car.
My car runs great otherwise. One time my trunk would keep opening by itself so we disconnected the wire in the trunk and now the doors are making funning sounds.
please hellp me....No one can seem to find the problem.

It sounds like a bad body control module (BCM). Here is a test to check for electrical draw. Chances are there will be one. While checking, remove one fuse at a time until you find the one causing the draw. Let me know what circuit is causing it.

Let me know what you find.
