Glen, the red wire according to the diagram I have is the hot wire. It goes to a junction that branches off from the fuse panel to the horn relay, directional signal switch and also to the light switch. So, if it's just the horn, I'd guess an open from that junction to the relay. You can tell for sure if the relay has no power going to it. Should be a dark green going to the horn it's self, the black wire goes to the steering column. Sounds like the switch on the washers to me. Check for power with a test light.

Sweet thanks man. Any idea if the motor is able to be turned by hand for the wipers? I think it may be froze. I figured out the horn. it was a bad contact from the spring to the little brass or copper pieces in the steering column
