Horn stopped working on steering wheel

Hi,

We know the horn is good, the relay is working, and the fuse is good. That leaves three things, the horn switch, cable reel (clock spring), or a wiring problem. If I had to guess, I would say the clock spring. Does the cruise control work? If not, that adds to that being the problem.

If you look below, I attached a pic of the horn's wiring schematic.

What I suggest is to check the horn switch before replacing the clock spring. If you look at the remaining pictures, I included directions for testing specific to this vehicle. Let me know if it is something you feel comfortable doing. These directions also check the clock spring (cable reel).

Here is a link that you may find helpful:

Let me know what you find or if you have other questions.

Take care,

Joe

See pics below.

Hi,

The cruise goes through the clock spring as well. If it works, then the spring is likely not the issue. Chances are it's the switch, relay, or an open circuit.
If you have the opportunity, please let me know what is found. I'm interested in knowing.

Take care,

Joe
