On the 2000 Chevy Silverado, there are two horns. Both are mounted on the front of the vehicle. One on each side of the radiator near the bottom.
The horn is behind the front grill on the passenger side.
The horn is located in the center of the steering wheel on the 2000 Chevy Cavalier.
Just pull straight out. If it is difficult you may use needle nosed pliers to pull fuse out.
in the fuse panel drivers side behind the door marked HORN
The horn relay on a 1989 Chevy Silverado is located on the passenger side of the engine compartment. It is way back on the firewall with several other relay switches.
