Where is the horn on an 07 ls?

The horn is behind and just below the drivers side head light behind the fender liner.

Unbolt the liner pull it back and it is bolted to the side of the sub frame for the front. All HHR's are in the same spot.

Single horn only.

Thank you, its pretty weak so I want to upgrade it. I would toot the thing and look all over can't find it! Another mystery solved.

I just added (to the right outside frame rail) an old GM horn (Chevelle, I think) that I had in my junkyard.
GM usta have a high and a low note when they were paired up; I dont know which one I used. Now, the horns are a lot louder, and they sound 'complimentary'. It is quite a unique sound, different than any other I've heard...

I also upgraded to a duel tone set of horns.

I stuck in a set of Hella hornes. I was able to use the original bracket and bolt both horns to it. I then cut the connector off and just wired it in with heat shrink connectors.

Make sure to aim the horns down to if any water gets in it will not go into the horn.

If someone cut me off with my old horn they would just waive at me thinking I was friendly. Far from it.
