Hi, my 91 civic gauge cluster lights have gone out, again.

The bulbs all go out at once. This will be the 4th time they've gone out completely. They start by going on/off randomly, then finally go out and don't come back on. I was thinking, since I can't be sure what parts messed up, i'll replace the whole gauge cluster w/a new one that comes w/new wiring.

What is the likely-hood of fixing the problem for good this way? I've only ever replaced the bulbs-but thats only a temp fix and is a huge hassle cause I can't do the work since I don't know much about cars, I have to pay someone to take apart the dash.

PLEASE HELP!
