replacing horns on 2003 silverado 2500hd diesel

Which Hella are you thinking of getting? Today I would have appreciated a Peterbuilt or Mack .... with the holiday traffic.

To locate the passenger side horn, either 1) open the hood and look straight down between the air filter box and the front radiator support (it's pretty far down and you'll need a flashlight to see it), or you can 2) remove the plastic fender well liner and it will be easily in reach in the front of the wheel well.

I've not bothered looking for the driver's side horn, but I can imagine that it's in the mirror image location.

On my '02 2500HD, if I lay on my back, with my head just under the front bumper (like if you might be replacing a fog light lamp), you can see the horn(s) almost directly above the fog lights. They're sort of "flying saucer" shaped.

Your horn relay should be in the electrical center (large black box under the hood on the driver's side). The top pulls up and off and all of the relays should live under there. If the horn relay isn't there, it in the fuse panel inside your cab - just open the driver's door and the access cover should be on the side of the dash covered by the door when it's closed.

Thanks
