Where Are The Horns?

I'm trying to fix all the "little" problems with my '97 K1500 Suburban, the horn is next on the list. It sounds weak and it's kinda embarrassing. I found a horn on the passenger side behind the battery that is working for one tone, but I can't find a second horn for the other tone.

 

Does this truck have two horns? I removed the washer fluid reservoir on the drivers side, but no horn to be found. Web searches on auto parts sites show high/low tone horns, where the heck are they?

Thanks to the helpful folks over at Fullsize Chevy I found that the second horn is in the middle of the core support behind the grille. That's the low tone horn and mine was rusted through. Replaced it and I can again honk the horn without feeling wimpy!
