run a hot wire to it, see if it works, I bought one from a salvage yard when mine quit, so the sound would be the same.

In the my 99, the fuse and relay and in the main fuse box under the hood behind the battery. On the backside of the cover is the fuse diagram. The two horns are located in front of the radiator behind the grill. Double check the wiring to make sure nothing is loose.
