Half of instrument lights went out at once?

Hey guys-

First, I wanted everyone to know that I searched the forum for a while and couldnt find an instance of this...

I was driving down the road in my ZJ (1996) last night when the left side instrument lights all went out. The instruments all work as they should, but there is no illumnation.

Thinking about this analytically, I can't understand what happened. Either:
1) I blew every bulb on that side at once time. Highly unlikely, I would think.
2) I have a fuse or relay to check. I was under the impression however, that 1 fuse was responsible for the entire instrument panel illumination...why would half work and half not if the fuse was blown?
3) on a side note, I suspect my battery and cables need replacing, and will do that this weekend. any chance that issue could be a cause?

Thanks in advance. I bought this baby with a bunch of miles, and want to help her live a long life.

hmmm I don't see anything in the fuse panel that splits the cluster into multiple fuses, I would check any ground for the cluster, fuse box and battery. And hope your circuit board for the cluster isn't screwed

Five cluster bulbs are all wired in parallel sharing common +12v and GND.
Not easily separated unless something shorted and melted the flex circuit trace between them.

Two bulbs on each side, one in the center.

Perhaps one left bulb was already out? Now the other left bulb went out?

oooh....good thought. come to think of it, the one center left may have been out already. might be an easy fix or at least a good place to start.

Getting the instrument panel out is very easy. http://www.installdr.com/installdocs...PDF/533013.PDF. Once you get to step 7 there you can remove the 4 screws around the instrument panel and pull it out, then change your bulbs.
