I've got a 1986 Corona with an AE86 steering wheel on it. The steering wheel was on it when I bought it. Horn didn't work, but I was sure it would be an easy fix. Checked the contacts by hand the horn worked. Tried 2 different boss kits with completely new steering wheels, even 2 different original Corona steering wheels from some friends who also have Coronas. But still nothing doing. Someone suggested that the contact may be too far down in the steering column for the wheels to reach?
Anyway, I was wondering if anyone else had a Corona with a similar issue and they knew a fix.
