The horn on my '98 Expy would sometimes stay on and the only way to silence it would be to remove the fuse. Unfortunately, this also eliminates the cruise control - which sucked on long drives. I troubleshot it to the plastic horn "pad" located between the leather cover (where you press to sound the horn) and the air bag. It looks like there are several kinked sections. There is a number: 32970203 located above the wire leads which eventually go to the horn relay, fuse and horn - and just underneath that #, it shows: TRW PNo 30308177A REV A, and underneath that, it shows: PRESSAC INC GTS. I did a little digging and found that Pressac is the manufacturer for these pads, but can't find the part itself anywhere. Anyone have any ideas how to go about getting a new pad - or do I have purchase the entire airbag assembly from the dealer?
