remove airbag according to shop manual procedures (legal) and inspect the horn contact plate. Mine had deteriorated plastic insulators that caused it to ground out and activate the horn

I got back from Afghanistan and after i got my yearly inspection the horn just started to get a mind of its own. For now I pulled the relay. I really need to get this fixed. I do all the repairs on my own and have never had a problem till now. I cannot figure it out. Being the year and mileage i do not want to spend a boat load of money if i can do it myself. please let me know what to do. A little help would be great.
