2005 Pacifica Horn Issues

Hi everyone. I'm looking for some input on my Pacifica horn. There are times when you push it while driving and it just won't honk without a lot of pressure. Today sitting in the driveway just pushing on it lightly I can get it to horn with one finger. It has always been this way since it was new. I've been leery of taking it apart because of the airbag system. Any thoughts?
