Horn Button Wiring

[gogmorgo]

So ever since I bought my MJ ('91 4.0 HO) my horn hasn't worked. I picked up a couple working horns at the wrecker the other day, and was going to replace it.

Then I thought to check, and realized the relay wasn't clicking. I couldn't find the relay itself, so I popped the button off just to make sure it was working and it didn't seem to have any wires going to it. Is this normal and I just need a new relay (where is it?), or is there something missing?

I pulled the wheel off and couldn't find any retracted wires in the column, but I didn't dig very far.

The horn will sound with a jumper direct from the battery, so I know that's not the issue...

The horn relay is behind the lower dash panel in front of where your right knee is. You should hear it click when applying a ground by pressing the horn button on the column. If you hear the click, the relay and horn button are okay. Sometimes the relay connector comes loose, and sometimes the internal column that rides the flexplate gets so corroded it doesn't make the ground circuit. First thing check the relay connector, then pull the wheel and check out the flex plate and horn button contact wire. It lives in a white plastic insulator with a spring on it like a ballpoint pen.
