Horn repair

Post by keith »

This is how to repair the horn ring when it wears down.

Remove the cover over the horn
Remove the horn contacts
Remove the steering wheel and turn it over.
On the steering column, you can see the brush that carries the current from the steering wheel down to the wiring harness and to the horn.

Image

On the bottom of the steering wheel is the brass ring that contacts the brush. By now the brush has worn down so that it doesn't make contact with this ring any more. Remove this ring.

Image

Cut a piece of adhesive backed gasket material to fit under this ring, between the steering wheel and the ring and reinstall.

Image

You test this first before starting by unlocking the tilt wheel and move the wheel to its upmost position, the horn will work, but not in the down most position, or visa versa. Its been awhile.

When I had to fix my Tercel's horn, I first raised the brass ring, much like you describe. However, I was concerned that the spring-loaded brush might catch on the raised ring, either causing the steering wheel to lock or bending/breaking off the brush stem.

So, I reseated the ring in its normal place then put a solder bead on the end of the worn down brush end.
No other vehicle that I have ever owned had a heart and soul like my 1985 Tercel SR5 4WD Wagon. :D

I do not think so, the indicator stalk is unrelated, it has a lever that strikes a post as you turn the steering wheel to disengage the indicator when going around a corner. none of that affects the horn ring.

That is assuming you got it all back together properly. It is possible you may have disturbed a contact, the alignment, or connector on the horn assembly when you had it apart. But I have found it is rare that the horn works anymore on a 35 year old car, corrosion and wear typically makes it not work without a good overhaul like shown on this thread.
