Has anyone solution for horn that blows continually? Had to pull fuse to stop it.

 

I'll bet it's the horn membrane switch - not something that just anyone can replace, as it involves removing the steering wheel where the potentially explosive airbag lies.

 

My 2000 had this problem. Have your chevy Dealer or your trusted mechanic remove the air bag unit. Most of the time it can be repair by Five Star Air Bag, Telephone # 501 988 0611 They are in Arkansas Website fivestarairbags.com for under $200.00 it takes about 2 week. The biggest issue is the removal and reinstallation of the Air Bag Unit.
