How do you fix a horn that does not shut off on a 2001 Mitsubishi Montero?

There is three areas you can look at, relays, horns and horn pad; unfortunately it boils down to the most expensive one of them

• HORN PAD. The problem arises from having a stuck horn pad which

turns out to be with the airbag; all one piece. OUCH!!!! Pricing for a horn pad and airbag is about $1,200 plus labor, rough estimate $2,000
