Horn Relay
Need some help, just got a 90 with a dead horn. The horns work, set the alarm and they sound. Mash the horn button, no relay click, and the fuse isn't bad. My 89 manual says it's behind the info center. Not so on the 90. Anyone have any ideas?

Re: Horn Relay (85vetteguy)
Thanks Guy.
Went down to the dealer and looked in their shop manuals. Looks like from 90-96 they are all in the same location, under the Rt side dash, right along the ledge where the bottom cover screws together. At least the 95 and 91 manuals say so. I didn't know if the computer completely controlled the alarm via internal relay or not.
Actually, they're both triggered by going to ground on the same wire, computer and horn buttons. I mainly wanted to know the wiring diagram to know where to look.
Fog lights, fuel pump relay, interior lights relays are also there.
Hope this helps someone else.

Re: Horn Relay (johnnyevans)
Looks like you got it figured out.
I was gonna say, unhook the horn, and set the alarm off, and listen for the clicking relay.
So.. you have a bad horn switch? My horn button takes a good whack to close the ground loop.
