Where does the damn horn ground to?

[cantspell]

Hi there, so i'm finally taking care of my beloved truck, and of the problems is the horn not working, but i've traced the problem to the horn it self...i've cleaned the connected that goes to that supplies the power, but where does it ground to? I've heard they can ground out - but i can't find the ground...?

Thanks!

According to 96 drawings (your 98 may be different), the horns are grounded "unto themselves"... that is the action of bolting is the ground. Are you sure you are getting voltage thru your horn relay? Once it gets thru there, its straight to the horns.... best way to check is measure from the input lead from the horn to body ground and see if you get a resistance. If not, then either the horns (they are in parallel) are bad (not likely both would go) or a bad connection / ground is a problem. If it is a short, then perhaps one horn or the other has a problem. Disconnect one and see if the other works.

Question, does your cruise control work? If not, I suspect its your clock spring. Mines is problematic.. Sometimes the horn & cruise control will work sometimes it won't..

Yup they ALL self ground

i've disconnected them individually and they still don't work, and i can hear the relay...work...when i hit the horn...but no sound!

have you verified + voltage to the actual wire leading to the horn? just because a relay clicks doesnt mean it is actually sending power, especially if there is an internal failure or even a wire snipped or cut internally somewhere.....

Couldn't you just run a positive jumper directly to the horn to rule them out?

The good / bad news is that according to my 96 drawings, the voltage to operate the relay and also cause "horn noise" is the same fuse / wire. Thus, it appears you have confirm voltage at least to the relay. As suggested, ensure it makes it thru the relay and also possibly try a "direct connection" to cause "horn noise"... beware, it is quite loud so protect your hearing if you are close.

Hey guys, THanks a lot for all the help, i did run a straight wire from the battery to the horns, didn't work, so i just went out and bought a new one and it works (unfortunatly i got the 'high tone', so my truck sounds like a civic?! but it's all good, it works, thanks!
