I have a 2002 Nissan Sentra SE-R that has an audio problem.  I have no left
side audio in my car (the right side is just fine).  I have tried adjusting
the left/right-front/back faders to no avail.  If I adjust the faders to
full left, and turn the volume up as high as it can go, I can barely hear
audio coming out of the left-side speakers.  However, when I push the
"AUDIO" button on the radio face, the beeping is heard evenly (meaning the
same volume) throughout all the speakers (both left and right), so I know
that the speakers are good (plus the car only has just under 15,000 miles
on it).  I have checked all fuses, and they are all good.  I don't want to
take my car to the shop, because I suspect that this may be a problem that
I can fix myself, however, I have no idea what the exact problem is
(faulty wiring somewhere, bad deck, whatever).  I just need to know what
the problem may be, and I can most likely fix it myself.  Any help would
be appreciated.
