I NEED HELP
I Drive a 2004 xb and i hate the horn. It sounds so funny people laugh instead of moving out of my way. So i installed a new horn and when i went to connect it i couldn't find the original horn. Please help if anyone knows where it is located in the engine compartment.

Did you get an air horn?

There are 2 horns on the B. Both are located behind the front bumper cover. One is on the driverside of the car and the other is in the middle of the car.If you climb under the car and look up you will see them.

You can see both horns easily in the third picture. You don't have to take the front end off to do it though. I was able to replace mine through the upper grill opening. People hear me now!
