liberty horn

My Liberty 2005 horn came on in the middle of the night. I disconnected the battery. How do I fix the problem. The horn won't shut off. It's not the safety locking system. It is a continuous beep with no lights flashing.

Pull the horn relay and use an ohmeter or test lamp to see if there is a ground signal on pin 85 of the horn relay receptacle. If no ground is present, that means the horn switch in the steering wheel is not causing the fault. Good chance you have a faulty relay, you should be able to find another in the junction block that is the same part number and do a swap to confirm the condition of the horn relay.

What Bnova said^^^

Check if you have a switch on the passenger side under the hood that senses that the hood is closed.

I have seen reports of problems like yours where this switch causes problems so the Jeep thinks someone is trying to force the hood to hot-wire the engine....this is controlled by the BCM.

I am not sure if the switch needs to be shorted out or disconnected to bypass the false alarms....try both to see if that stops the horn blowing.

I have also seen a post where this switch was sticking so a spray of Q20 fixed the horn blowing issue.

Clock spring

You might have someone check to see if your clock spring needs replaced. We have a 2002 liberty, and the horns did not work when we purchased the car used, I found the horns disconnected, so I reconnected them. Then every time I turn the steering wheel the horn blew.

The fuse panel inside the cabin is actually called the Junction Block.

If you remove it and flip it over you will see a whole lot of relays...not marked.

You can download the 2006 KJ Service Manual here...includes wiring diagrams...section 8W.

The wiring diagrams will give you a picture of the front and rear of the Junction Block so you can find the correct relay and swap it out with an identical one next to it.
