A few months ago, I replaced the bulb in the driver's side map light. Not too long after, the passenger side light quit coming on when I opened or closed the door, and wouldn't turn on when I turned the switch. I figured it was another blown bulb. I finally got around to replacing the bulb. In the course of popping off the cover to replace it a few days ago I pressed the light, and it turned on. I replaced the bulb anyway. It started working after that. However, now the driver's side light has quit working when the door is opened or when you use the slide switch. If you press the light cover, it turns on. Any suggestions? Im thinking there's a loose connection in the fixture somewhere.
