Welcome to JA
Have you check for power tothe horn button,?
Has there been any recient work done on the car?
You can run a push button from the horn to a switch to a fuse power supply,
I think your having a problom with a clock spring.
you don't want to tap into the factory wiring
wrong wire will discharge the air bag.
THis will get you a temp horn until you have funds for a clock spring
Let me know if i can help more!
Here is what you need
A push switch
4 wire ends
20 feet 18 gage wire
1 ,15 amp in line fuse
Dis connect the factory wire from the horn
connect your new horn wire to the horn
run back to the dash
run a power supply off the battery
about 1 foot back from the battery
add the in line fuse
run the wire to the dash
connect the 2 wires to the switch
mount switch to dash
ready for the inspection
