Hello all. I've search the forum for my particular horn issue but didn't find it.
Issue: Horn is constantly on when everything is hooked up.
When: I had the TJ outside (Garaged now) with a tarp over it. The Roof is okay with minor leaks at the threaded seams so I wanted to make sure it was dry. We had a lot of rain back to back. One afternoon it started going off. That was a couple years ago. I thought maybe something to do with the moisture.
What's been done: The clockspring was replaced about a year prior to this because the Air Bag light was on. I replaced the clockspring and the light went off the horn worked. I replaced the horns with new ones. They sounded good, no issues.
Testing: I've taken the clockspring out and tested the continuity through it, which was good. I've swapped relays and nothing changed. I tested the horn switch in front of the air bag. There is continuity when the switch is pressed. I even took the air bag out to look at the switch. Nothing looked out of place. I really thought that was the issue. When I touch the horn wire before the clockspring to ground, it beeps. I touched the horn wire after the clockspring, it beeps.
When I attach the clockspring horn wire to the horn switch wire and ground the air bag case, it beeps.
I hooked up a push button in place of the horn switch. When I press the switch and close the circuit, it beeps. I press it again to open the circuit, it stops. Isn't that what the horn switch does? Just closes the circuit when pressed?
Side note: The windshield washer no longer works. I didn't notice that before. Not sure if that is related. I've read others mention the same.
Any help is appreciated. If I overlooked a thread with the solution or guidance, I apologize. Please point me to it. Thanks!
