OK, here's one for the under-dash wiring experts.
My horn quit working. Doesn't work with either the steering wheel switch, nor the alarm. If I jumper from the second connector on the column (down near the dash) to the relay, the horn sounds. I'm surmising that somewhere at the point where the steering wheel-switched wire joins the alarm switched wire, there is a problem in either the logic, or the hardwiring.
I can just jumper around the alram with scotchblocks, but don't really want to cobble it together, although, I really don't need the alarm.
Anybody had this problem and fixed it?

are you sure the relay is good?i looked up the wiring diag and the horn and alarm comes together before the horn relay at s2117.(this is for a d1 for 97-99 model years,not sure what you have).after that point the alarm uses the same circiut as the horn.you need to see if you have a ground being applied to term 86 on the horn relay with the horn button pressed.if you do you should have power at term 87,if not the relay is bad.after the relay it goes right to the horns.aslo check fuse f4(engine compartment fuse box) hope this helps.Don |

Yep, that's what I meant by saying I jumpered from the steering wheel switch to the relay (confirmed my presumption that wiring from steering wheel switch to jumper point, to relay to horns was continuous, eliminating anything that could have been alarm related). I could still have a broken wire somewhere between where the horn and alarm wires join as I do not have a continuous circuit between the horn switch and the relay.
There is a big multi-conductor connector (c2012-I think) and it is somewhere after this connector that things fall apart, hence my thought it had something to do with the alarm. At this point, the wiring harness becomes very intimidating and runs back behind the center console portion of the dashboard.
reference page e-5 of the wiring diagram.
