Horn not working

Hi all I have found the two fuse boxes for this vehicle. one in the trunk the other on the left side of dash. Everything I read says its 40 and 41 or 42. All of the fuses are good. Can anyone verify if there is another fuse box under the hood?

I could not find it.
Also the fuse numbers are only 5 amp and 7.5 amp

Another poster vermbird wrote: "all right! i found the fuse! its #41, way in the back of the fuse box near the booster. it is not in line with the other fuses, offset a bit. it was 15 amps."

Where is this fuse?

Any help greatly appreciated as my wife drives this car and I am concerned for her safety.

Drew

Solved

I found the SAM in the engine compartment, it was on the drivers side towards the firewall. All was good fuse and relay, turns out the horn in the front by the grill is bad, So I ordered new horns online. I will update when I get them in a couple of days.

One note after all this digging I found that a fuse that is next to the offset fuse can be offset to the right and the Cigarette lighter will always be hot. (This is good to charge your cell phone while you are in a store or whatever)

Thanks for all of your help
