According to the 2001 to 2008 C5 Haynes manual, the horns are located at the front end of the vehicle and are accessed by removing the front bumper. It looks as if it is at the left side, a bit below the headlight so in the wheel arch side of the inner wing at the front. I am not sure, but it may be possible to get to it by removing the undershield in that corner. There are 2 horns, one with a high note and one with a low note, with different parts nos. Later I will move this topic to the C5 Technical subforum.
