It is the horn ..
The pic below shows how I modified the bracket so that the horn points downward like the horn on the right side of the engine bay.
I took the horn off, removed the bracket and bent it downward after studying how much and where to bend it.
It still clears the A/C line below it by about an inch. And the wires to the horn also accommodate the modification also.
No big deal to do it.
In 2020 onward it is mounted downward.
No idea why they had that left horn sitting like it was on 2017 to 2019.
Every time I opened the hood I couldn't stand how ridiculous that looked.
