Having problems with your 1999 Chevrolet Malibu ?
I have the exactly the same car and same horn problem.
\015 My Chevy Malibu 99's horn does not work. I connected wires from battery directly to the horn and it works. I checked the voltage of the incoming wire and there is no voltage.I checked the horn fuse and it is as good as new (tested too);I checked the horn relay and it does not seem the problem.Now, it left only one possibility: the switch. But it connected with airbag so I don't know how to open.\015
The best advice is to let a proffesional look at it . if the air bag goes off, then you are looking at a few hundred dollars to repair.
