Electrical problem
1991 Cadillac Deville V8 Two Wheel Drive Automatic 142600 miles

something is killing my battery. When i put my fuse in for my doors lights it works but when i close my door only some will go off.Is there a way to check that without having to go to a dealer

Go door by door and check each door contact switch. See if rubber bumper is on switch.Take switch off check for operation. switch closed light on. open light off.
