Here's a easy fix if your horn is inop but still works with key fob.
Remove the air bag and there's a white post connector with red wire's coming out of it, Turn plastic post slightly clockwise to remove be careful not to break post and then clean contacts and reinstall should be working now, Here's some pic's.

This is true! Worked for me last year. I did a search then and didn't find that anyone had this problem.

Yep did the search also and found nothing like this fix either!

My horn has been intermittent for months now. Figured the contact is dirty. Got to get it fixed.

Can anyone tell me how to remove the airbag? Tried the search for but came up with nothing.

Thanks!
