New one today - wife drove her X5 home and parked in the garage. After roughly 5 minutes the horn starts blow and she can't get it to quit until roughly 25 minutes later when the fuse blew.

I replaced the fuse several times and as soon as I hit the horn button on the steering wheel (airbag) the fuse blows with just a whimper from the actual horn. Without the fuse in place I can hear the relay activating but only when pressing on one corner of the steering wheel button which also seems odd.

I have searched and found that the e46s had issues with the horn button but didn't see anything related to our X5s.

I am guessing something to do with the steering wheel button. Not sure if simply taking the airbag off and inspecting the horn contacts would reveal anything obvious but that may be the place to start.

Anyone have experience with this issue or advice?

Thanks in advance
DJ
