Help with 1992 Rodeo Horn
 

Horn only works sometimes...fuse is good, Manual I have (Chilton), doesn't show electrical diagram for horn at all. Anyone know if there is a horn relay for this model/year and if so...where is it?

Thanks!

I believe there is a relay under hood passenger side, HOWEVER....
I have been banging my head against the wall with my 92's horn. With multiple meter check the contacts where connects to horn while pressing horn, if you have no one to push horn, take off steering wheel center cap and run a jump wire from from center steering wheel bolt to wire connector just above bolt. If you get nothing you may very well have same issue I did. Found wires (black and orange, green and orange were broken internally about 3inches down from horn itself. I cut them/spliced with new wire and all Is good! Good luck, electrical is a PIA! Multiple meter is your best friend!
