Horn Issues?
 

On my 04 yukon denali the horn has a mind of its own? Sometimes it works perfect and other times only the high tone horn works and sounds like an damn clown car! I don't know if i just replace the low tone if that would solve the issue or if there is a short somewhere? Of course the dealer wants me to bring the truck in so they can look at the problem! Anyone have this issue before?

Sound like the low tone horn is bad or has a loose connection to it....

could be an open circuit in the wiring to the horn, but my guess would be that it's the horn itself

my '03 and now my '05 is doing the same thing...when it is raining it will stop working alltogether or if the wheel is turned the horn wont work, other times it works no matter what...I have had 3 gm vehicles with horn issues...:bang:

my low is gone too, I only honk if its an emergency...If someone's in my way I just open my e-cutout:devil:

check the relays and fuse box. as well check the BCM for loose connections. If all else fails just disconnect the stock horn and buy a air horn :D. you will be scaring the crap out of people in no time!

Hell I don't know if I've ever used the horn on mine.

my horn sucks...i honk and people look around for the geo metro.
