hey, I have to get my car safety inspected and I need my horn to work. It has worked before, but I disconnected it one time when I was rooting out an electrical problem and then I couldn't ever get it back to work right. When power is directly applied the horn still honks. When it worked before all it was wire through was a simple relay thing. It has a diagram on it with the numbers 85,86,87, and 30. It had two power wires, a wire to the horn, and one other I think it was purple, black, and dark blue. something like that.
any help is appreciated
thanks

The year would help. Sounds like a late 70s/early 80s car with those relay numbers.

oops sorry. Its a 1970 malibu. The original brass cover relay was removed, when it failed and was replaced with one of those relays you can buy at the parts store that is black. That is what those numbers are from. I just can't get it to work. thanks for any help

Should look like the relay in the attached link. 85 and 86 are the coil contacts.
87 and 30 are the switch contacts.
The horn is tied to either 87 or 30, right?

So this is probably the most random thing I have had break in my car to date. It was the spring that holds the the horn contact button on the copper ring that rotates as you turn the wheel. I'm glad I have an uncle that is an engineer. So we used a ball point pen spring and bored out the little copper cap thing just a touch and tada it honks. Thanks for the help guys
