The bulbs are probably blown. This is fairly common on an "older" vehicle. If the miles are high, then I'd say that's more than likely your problem. It seems like they all tend to go out at once. Replacing the instrument panel lights should be fairly easy. Remove dash cover and it should be self explanatory from there. As far as the heater controls, those may be a little more difficult to replace. The bulbs in my '93 lumina did the same thing. I took the heater control box apart and found that it would be quite difficult to replace the bulbs and get that thing back together properly. I also looked up the replacement bulbs in the owners manual, but couldn't find any place that carried them. I didn't check Radio Shack, so you might try that if you want to mess with trying to replace them. I saved my energy and just got used controls in the junkyard (around $10) and it's worked fine ever since. You run a risk in getting junkyard parts, but the cost is considerably less than purchasing a new one. If/when you replace the box, be sure to put all the wires back in the proper place. Good Luck!
