I have a 2003 Maxima GLE. I found that, after fixing the wiring harness behind my factory Bose stereo, NONE of the lights (instr. panel, stereo, A/C) lights worked. The problem was a burnt out fuse, so I replaced it and the stereo and A/C lights began working again, but only when the headlights are off. Now, whenever I turn the headlights on, the instrument panel lights don't come on, and the stereo and A/C lights go off. The only lights that still work on my instrument panel are the service engine, cruise control, gas tank, and any other indicator lights, as well as the clock above the dashboard. I followed the wiring diagram here
5th Generation Nissan Maxima Wiring Page and everything is configured exactly as it should be, but I am still having this problem. I just went through the fuse panel next to the steering wheel, removing EVERY fuse, and they are all in working order. Does anyone have any idea what could have gone wrong??
