I had an accident and my Max was in the body shop for about 4 weeks. I guess they disconnected the battery because the clock and radio presets were off. Also, my sunroof won't slide open, but the vent still works. I remember seeing on here what you need to do to reset the sunroof. I tried doing a search using yahoo and sifting through some old threads but I couldn't find it.

 

i hope this helps...http://forums.maxima.org/showthread.php?t=325411
