don't work anymore...why? I recently installed a dvd player in my 1997 nissian maxima. It worked momentarily but now neither it, my cigarette lighter or clock work. I checked my fuses and replaced my cigarette lighter fuse (thinking the three were connected and it was a simple fuse issue.) None of this basic trouble shooting seemed to work. i'm at a loss for what it could possibly be.I recently installed a dvd player in my 1997 nissian maxima.
