My 1994 Voyager Owners manual, 0n page 176-177 tells me that the Horn fuse is a 20 Amp(yellow)fuse that is located in position 3(Three)in the fuse panel. Besides the horn, it should also provide power to the Cigar Lighter, the Horn Relay and the speaker amp.

Both, the horn relay and the horn fuse are located under the dash panel on the left side of the steering wheel. The fuse is a 20 amp fuse, lower left side of the fuse panel (which is somewhat difficult to access...especially if you have large hands) on the firewall. The horn relay is located above the fuse panel on the branch of wires coming out from the rear of the fuse panel.

Behind the fuse panel. You have to remove the fuse panel located in the drivers side kick panel and mounted on the back side of the fuse panel are a cluster of relays. One is for the Horn.

It's the 15 amp CTSY/CLK fuse on the fuse panel. The fuse panel is located on the right side of the instrument panel. Open the passenger door and you will see it.
The horn fuse on a 1999 Chevy Express is located in the fuse box under the dashboard on the driver's side. You can find the fuse box by removing the cover panel below the steering column. Look for the fuse labeled "Horn" in the fuse diagram on the cover or in the owner's manual. If the fuse is blown, it will need to be replaced to restore horn functionality.
