Switch quit working. Replaced fuse but have no power at the fuse. Help. Also, where can I get a diagram of what the letters on the power distribution box work, have no owners manual?

 

yep all that stuff works and is back together except the interior lights don't work on the door switch and the horn and the airbag doesn't work. i have the steering wheel off and the wires to the airbag are broken and i don't hear the relay for the horn clicking. and when the car is running i hear a light tick. but it runs and drives. not bad for 100 bucks.
