Thanks for your reply
Yesterday I checked the horn and it was working and it's working today as well. I think you are right about the steering wheel being sensitive. Then again before I would press it every where on the steering wheel and it wouldn't make a sound and all of the of the sudden it's working again. This is still a safety hazard. I'm going to give it another week to see what happens. Hopefully it won't give me anymore problems.
I did contact GM corporate and told them about the problem. They've been working with me.
Thanks again!
