The "low" horn on my 2006 S40 stopped working. I've ordered a new one, but can't figure out the best way to access the horn (located just behind the grille). Does anyone know or have a diagram of how to access the horn for replacement?

 

Welcome to the forum.

I don't have the instructions for the 2006 model but I do have them for the years before. Up to 2004 this was a simple operation of removing one nut, a connector and the horn. Replacement was the opposite. For the 2004 and 2005 models the front bumper has to be removed and I would suspect the same for the 2006.

Is the vehicle out of warranty?
