My horn goes off at times and won't stop. When it does, you can hear a soft horn sound, and I think it drains my battery. Do I need to disconnect the horn, and if so, how do I go about doing this?

Hello,

This sounds like it's due to a wiring issue for the horn.
It could be shorted to the ground and providing contact power to the horn.
You will have to trace the horn harness and find the short.

Here is a helpful guide on how to check wiring:

I have attached the wiring schematics for the horn below.

Please let me know if you have any questions.
Thank you.
