Question about 2007 Volkswagen Jetta 2.5 Sedan
The problem may be that the horn is faulty or the horn button on the steering wheel is not making contact, check for loose wires & connections, to check the horn remove the wire(s) from it then connect a wire to the positive terminal of the battery then to the horn if the horn is OK it should work if not it is faulty & will need replacing,if the horn has two wires to it you will need another wire from the negative terminal of the battery to the horn as well........hope this helps......cheers

If it has an airbag than take it to a mechanic, but if not then try popping of the steering wheel cover and inspect the contacts points to complete the circuit for the horn to sound. Also check the wiring to the horn, it coul be loose or the horn could have gone bad.

It sounds as if your BCM Body Control Module is failing. Nearly all electrical controls go to this on these vans. Best to purchase aused one from a wrecking yard. If my memory sereves me the BCM in located under the hood, drivers side by the fuse box.
I hope this may have helped you,

Either the owners manual or the cover on the fuse box should have that information. On nearly all cars you can just look at the inside of the fuse box cover.
