My first guess would be the ECM or electonic control module, also comparable to a PCM that is used on cars today. You can find an ECM replacement for your vehicle, if you have trouble locating one try an online parts locator, this is a free service. I would like to add considering the age of the vehicle: I would strongly recommend purchasing this part from a provider offering a full warranty. This could save you a lot of frustration as well as money in the long run. I've run in to this problem in the past when buying replacement parts that are no longer manufactured. A seller offering a warranty may cost a little more but offers you potential money pit protection.
And that can be priceless.

My radio, ac, heat, cigarette lighter, clock went out. Does anyone know which fuse I need to change? I don't have a manual book to tell me which exact fuse I need to replace.


Sounds like the most obvious place to check is the cigarette lighter and its fuse, many times folks stuff a penny in the lighter port without realizing it and cause the fuse to constantly blow.
Now finding the fuse panel is fun....not really....buty it is there don't give up!!
under the dash where you rest your left foot on a drive...the fuise panel is to the left side kick panel half buried by the carpeting, it is has a black flat cover marked fuse, open it and the whole fuse arrangements are clearly and consisely marked for replacement.
Happy Motoring!!
