So the horn has slowly been going out on my '94. I really thought it was the switch in the steering wheel because if you pressed it enough and sometimes hard, it would work. And it doesn't get much use. But that's not it. No longer works period.
Started troubleshooting. Switched the relay with the ABS relay next to it (Assuming that's good since I don't know of any ABS issues.) No change. Relay clicks when you hit the horn, and I sent 12V to the relay and verified continuity between the correct pins on the relay.
Checked for 12V at the relay for horn power. Checked out fine. If I jump the pins in the power distribution box, I get a horn. Works perfect.
Even though the relay is clicking, checked for continuity between ground and the relay switch side - good.
So I'm lost. Relay is good. Horns are good. Cleaned the contacts on the relay and tightened up the contacts in the power distribution box (Making the relay really hard to get in and out now) - nothing. While someone held the horn, I plugged the relay in, wiggling it about to make sure it's getting good contact. Nada. Even pulled the power distribution box and watched the wires as I plugged the relay in to make sure one wasn't slipping down (Doesn't look it.)
Any other ideas?
