My horns were grounding out at the column, so I took it apart and found that the small insulated ring under the brass contact wheel on the crush can was completely deteriorated. I replaced that with a grommet which seemed to work perfectly. Problem now is- when I put pressure on the top of the steering wheel itself and press down- the horn goes off, so I still have a grounding issue, right?
Is there some insulator or spacer that prevents the crush can from making contact with the steering column where they meet?
Thanks
