i honked my horn the other day while crusing and i couldnt even hear it over the motor. then when i came to a stop i tried it again and it sounded horrible. is there any way to fix or clean them so i can get a good crisp sound out of it again?

clean the ground connections real good and spray a bit of wd40 into the horn

In addition to the above (if needed)most GM horns have a small screw near the base. This screw can be turned to adjust for tone quality, sometimes a small twist will cure a "weak" horn.

"SOUNDS" :haha: like they are just tired out new ones are cheep.

Jump a wire from the battery positive to the horn wire terminal and see how it sounds. You may have a loose wire on the horn relay or the relay may not be making good contact inside.

well i took the horns off, put aircraft paint remover on the connections to clean them real good, and sprayed wd40 down the horn and they sound like brand new now. thanks for all of yalls suggestions.

Another happy camper.;)
