Door Ajar Light

You wrote you had them replaced. I would take it back to the person that replaced the radio/ speaker and let them know what is going on. It sounds like the switch on the drivers door, "the one that tells the system the door is closed" is loose, broken or maybe a wire to it inside the door panel is shorting out.

make sure the push pin that sticks out is going in or is broken off,eather way you can unplug it from under the dash,other side will still work.

the person that replaced them was a friend of a friend and can not get contact with. Guess I'll need to take the car to a shop now, which will probably cost me an arm and/or leg. Thanks
