why wont my radio work after i tried to fix my horn in the steering wheel on 1991 Chevrolet Corsica

i tried to fix my horn and when i put the airbag back on it went crazy now i have no radio no interior lights what can i do to fix this i need the radio screw the horn

It's got to have a blown fuse/fuses.Horn fuse is 20 amp fuse #11 also powers radio.check fuse #14.
