Default Headlights, etc not working

I have a 69 coupe that I have been working on for a year now and we have put the grill and the lights back (and plugged in) but none of the front lights work (headlights, markers, turn signals) The rear tailights work but not the side markers and the reverse light are not hookedup. The fuses look fine but the manual didnt list a location in the fuse box for the headlights. Is there another relay or fuse location I should check? Also, the blower motor and the horn doesnt work either, windshield wipers are fine. Thank you once more for your help.

you need to get the wire diagram from the sections aboveand get after the circuit with a voltmeter or test light.

There's power in two spots on the plug although I couldnt tell ya which ones. It says the are two circuit breakers in the headlight switch itself which in seems are sealed inside and no apparent way to reset them if they are tripped. Should they reset themselves and I need to look for another connection?

Is the switch old? You might try a new one. Check the bulbs in the marker lights. If the tail lights work the markers should too. Do your dash lights and dome light work?

I bought a new switch and it made no difference.BUT after checking voltage on different plugs and putting the old switch back in, they came on. go figure. A couple of the bulbs were either loose or burned out but they ALL work now. so BIG THANKS to you guys who took the time to reply and I will see you at the next light!

Mine did that when I bought it. Pull your light switch out and there is coil on it in a half cicle. That is for the dash light dimmer. If it is burnt then replace it.
