Does anyone have the Horn wiring diagram for a 2011 Expy? I have no horn. No power to the horn assembly.
The horn assembly tests fine by jumping, sounds both high and low.
The #23 fuse on the passenger compartment fuse panel is fine.
Pulled the honk pad/steering wheel air bag. The honk pad is working fine using a multi meter to check continuity.
I am most interested in checking between the fuse panel and the clock spring connector/harness to determine if there is a short between the two or if it is in the clock spring.

Thanks in advance

I had a bad clock spring doing that. Think the other controls were fine. If I used the keyfob and locked, the horn worked, just nothing from the wheel.

When I use the fob, I get flashing light but no horn sound.
Then it is something past the clockspring. You will get to trace it backward then with a wiring diagram. I have seen one online somewhere, but don't have it.

Hey Donn…
Whatever happened with the horn issue ? I’m having the same exact thing going on . It’s like something cut the voice box everything seems to be working as it should just no sound for the horn and the alarm when set with the fob or side controls? I’d appreciate it if you could let me know what you found..Thanks!!

What trim level expys do you have? Possible retired law enforcement units? i have a retired US Forestry Service and the wire under the dash from the horn was cut in order for emergency lighting/siren equipment.

Interesting. We bought a used law enforcement car 2 years ago and the horn has never worked. Now I know what to look for!
