air conditioning display light

my 1992 accord's airconditioning/heater display turned on when i first bought the car, but it no longer does. is this a problem with the fuse, or with the wiring?? can i fix it myself, and what will i need to do so

dont laugh but on my 93 sol after i turn my headlights on I have to hit right above the AC controls once and then the lights come on. I though about taking it out to look at it, but i have better things to do. It makes my car unique..hah. Anyway try that, maby try opening and closing the golve box one, that works for me too. If not i dont know how to get the unit out. Hope that helps

yeah, mine will randomly turn off or on if i thwack the dash right at the a/c / heat controls... it's probably just a little corosion or a wire that works loose. normally not a big deal, i don't even look at my controls anymore anyway, just do 'em by feel at night.
