The headlights are not fused, they have a circuit breaker built into the main headlight switch on all GM built cars and trucks. If the headlights are not working most likely the headlight switch and connector will be burnt out, the contacts will be discolored and the connector smell burnt, replace both, the parts are fairly cheap
There is an electric actuator on the front axle that engages 4WD. This part commonly fails resulting in no 4WD. Unhook the electrical connector to this part and see if heater still blows fuses. If It does not blow the fuse, the problem is in the actuator. If it still blows the fuse then it could be in the wiring. Buy a repair manual and trace the wiring schematics.
There is a switch under the dash that is actuated by the brake pedal arm. Take a look at that and make sure it is properly being depressed or released with the movement of the brake pedal. You will need someone to watch the brake lights while you mess with it. Good luck.
I hope this helps a little, you said the fuse box panel is gone....so how do you know some fuses are missing?
I just bought a 1988 silverado also, the wipers ,power windows and windshield washer fluid only work "when they want to" I think I have a bad ground somewhere.
