The horn doesn't work on my 2003 BMW X5, is it a fuse? thank you.

coppper, have you checked the fuse with a test light yet?
If not I would check that first before going through all the trouble to get the fuse out.

fuses are all good, is it the horn switch on the wheel or the horn itself maybe?

try check power at the horn itself. If no power then disconnect the battery. goodluck!
