I noticed a few weeks ago the horn started blowing while turning the wheel. The problem has gotten worse, happening more often and with the lightest pressure on the wheel or even a bump in the road. It is also happening just driving and it seems to want to get stuck. What could be causing this? Is this something I could possibly fix myself? Thanks in advance for any advice.

Looks like the horn buttons are weak and self activating. You would need to remove the steering wheel pads to do it. If vehicle is equipped with air bags, extra care has to be taken and it is recommended to disconnect the battery negative terminals and wait a few minutes before starting work.
