Default random horn blown while driving down the road

I think I have a membrane going out. I was cruising down the road and all the sudden the horn started going off. I hit the horn button several times and it stopped. Afraid to try again I did not hit the horn again and did not lock with the key fob. I started searching the forums and found out about the membrane. I found that I should remove fuse 11 until I can get a new membrane installed. I went outside and pulled 11 and it was blown already. Does this sound like membrane failure to you guys??? Sorry for the long story.

Yes, it sounds like you have a membrane issue.

However, the fuse should not blow from horn use unless maybe the horn is on for a very very long time.

The blown fuse is what made me rethink membrane. It only blew 5 seconds then a few quick times as I tested it to stop the horn during the same time. Possibly wiring issue or a short ?

Not at home but I can provide a schematic for you and guidance on membrane replacement later.

Thanks for the schematic!

I'm not sure why my fuse would blow from a membrane issue? The horn only honked for about 3 seconds. That's not long enough to blow a 20amp fuse.

You did not say what year you have so this is from 2001. I think all the years are the same with the same wire colors. I can confirm if you told us what you have.

This has the schematic and how to replace the membrane.

There are more links on replacement if you need them
