So I was out diagnosing my faulty horn today and I found the culprit, the spring "finger" contact that contacts the steering wheel hub wasn't contacting. It works like a needle on a record to make a free spinning contact. Behind the steering wheel hub.
What are my chances Toyota still carries this part?
Anybody got one? (76 FJ40)
My other option is to fab a new one...
At least I found the issue, it broke when I tried to manipulate it into contacting the hub again. I must have worked it like a paper clip for too long.
