Arrow HELP! - Horn Stuck ON!!

Whenever I install the 20 amp horn fuse, the horn blasts, even though I'm not pressing on the center of the steering wheel. How do you get access to/replace the horn switch?

Try replacing the horn relay first.

To get to the horn switch, disconnect battery first so airbag doesn't blow.
Couple screws from backside of the steering wheel and you can remove the airbag.
Then you can get to the switch, but the "clock spring" flexible printed circuit is just as likely the culprit.

Are there any tests I can do on the horn relay instead of just replacing it? Can I swap with with another relay for testing?

Thanks for the help. I'll try swapping the relay with another one in the fuse box and report my results.

Before replacing anything, try loosening the two captive, 3/8" bolts which hold the air bag/horn pad on, first, of course, disconnecting the battery and allowing any residual current to dissipate. Occasionally those bolts get too tight, or something might have gotten wedged in between the air bag/horn pad, and the steering wheel.

Good idea! These are the bolts that hold the airbag to the steering wheel? Where would I find these bolts?

Update:

- Tried swapping horn relay with another known functioning relay, horn still stuck on
- Loosened the two airbag bolts recommended by mainest, horn still stuck on
- Removed the airbag and didn't find anything wrong with the horn contact strip or spring mechanism

Only thing left is replacing the clockspring, correct? I'm pretty much out of ideas.

You would need the horn pad, so if the clockspring comes with it then yes.

From what I can see, the horn pad is part of the airbag, not the clockspring. I checked the contact strip behind the airbag which grounds the horn and it isn't touching anywhere and looks clean.
