How do you silence a horn on a 1989 Jeep Cherokee?

try looking under the passenger side front end from the ground, there may be a plastic shield covering it (where u would wire up fog lights)

press the middle of the stearing wheel like a normal car?

I am guessing that you have a 4.0, I have that motor in my jeep and I run at 210 all the time.. that seems high to me but everyone says it is good.. I hope that helps I redid my cooling system,...

passenger side, front of engine,located at the bottom.if you slide under the jeeps passenger side front wheel you will see it.

It is self adjusting on a 89 Cherokee with a in line 6 4.0
