I have a 2007 Chevy Malibu with a stuck horn. I have already pulled the fuse, what should I do next?
Look in the owners manual and see if it indicates where the horn relay is located. Once located, swap the horn relay with another relay with the same part number. If the horn stops blowing replace the horn relay. If it continues to blow after swapping the relays, then the problem is most likey with the horn contacts inside the steering wheel.
