94 GA - No Lights

I was recently handed the keys to the 94 GA GT which formerly belonged to my son, who died in Jan 05. The car has been sitting under a lean-to since then. I jumped it off to get it on a trailer and brought it to the house. I have replaced the battery and the passenger door glass motor. I have NO lights. Radio, door locks, heater/ac, windows all work fine. I have no headlights, tail lights, turn signals, markers, dome light, etc. I checked all of the fuses in the panel in the dash, all looked good. I don't know how to test the three canister looking fuses in the lower right corner of the fuxe box. Before I haul this thing to an auto shop, I thought I'd do some internet research and see if I can't come up with some suggestions.

When my son had the car, he had an aftermarket stereo in it. During the time it sat, his brother and mother removed the aftermarket stereo and put the original radio back in it. It is working fine, but I wonder if they might have unplugged something up under the dash that didn't get plugged back in.

The info I looked at, was with DRL, daytime-- running-- lamps. It shows a headlamp circuit breaker--20 amp. I'd also check the tail lamp fuse--20 amp. My info shows those circuits are hot all the time. You just remove the fuse and breaker, check for voltage at one of the terminals for each. If there is nothing there, you backtrack the circuit.
