I'm honestly not sure where the horn relay is in these cars but my guess would be near the fuse box. The clicking you are hearing is likely the horn relay.Thanks for the diagram. I checked the CTSY CLK fuse, and discovered there was a 25amp fuse installed instead of a 20amp. I'm not sure if that matters, but I switched it out. I rechecked the green horn wire with my multi-meter. I still don't have voltage to the green horn wire. Any idea how I would go about checking the horn relay? Just to note, each time I press on the steering wheel horn button, I hear a "clicking" sound.
Just in case anyone has this issue, it turned out to be the horn relay switch.
