I bought my 1998 Z71 with the horn not working, gave a niggling jerk room with toll, but figured I could figure it out on my ain.
1.I first tried the wire jumper on the fuse console under the hood and nix. I even pulled the relay out and put information technology in our '95 cheyenne and the relay was in working club. Dad pointed out why non switch out horns and come across if it is any good. Figured what the heck why not. Well horn still works...
2. Had my dad hit the horn while I was touching the relay and no clicking... put a test light on the relay terminals and on the two closest to the back, not towards the front of the truck, had ability to them.
Kinda figured it is behind the steering bike with the AIR BAG. Do non feel like messing with that and did not realize even after looking at the wiring that there are two horns...

SO long story brusk I decided to BYPASS with a 12v inline fused link to a HORN button and then a signal wire out to the horn inside the cab. Well it worked simply only out of the Passenger's side horn, which sounds atrocious. I tied into the GREEN wire on the horn right under the hood latch assembly and so plugged it back in.
WHY CAN'T I GET SOUND OUT OF BOTH HORNS?

The schematic shows a diode in there. I would check information technology and the capacitor also shown. A blown diode would definitely prevent voltage from getting to the horn and it could possibly be a factor in your exam not working. Also check the quality of the ground. You could take a fine relay and those components could exist the consequence. Remember the diode is supposed to laissez passer current in simply i management. Check it with a Volt / Ohm meter.

I checked the relay on another truck and information technology worked fine, along with the horn itself. My problem now is, later I tied into the existing wire on the horn with the bypassed push button, only one of the two horns makes a sound. I have yet to bank check the ground but figured the two horns were grounded in the aforementioned spot. Ability/Signal is being sent through the one horn and onto the other. I did also check the horn as well with the other truck.

Here are the diagnostics for a 98, mayhap information technology will help. Not certain why both horns don't sound with voltage on circuit 29 unless you take a footing upshot between the left horn and splice 128.

The problem still smells similar a ground to me. If 1 horn ground connect is tied into some other one, e.grand. two lugs under the same screw, oxidation at that betoken could very hands give a bad ground to the 2nd horn. I wait the diagnostic steps provided above by Eastward 302 will find the outcome but my bet is still on the basis (or a blown diode). Delight written report when you find it!

Might want to cheque the Multi Part Switch on the steering column, just had a like situation on my 96 Yukon. Troubleshot it to the MFS, the black wire in Footstep 11 in the chart higher up is a ground wire for the horn relay. The circuit wasn't making it all the manner to the horn slip ring on the steering wheel.

I have had like problem with my 98. Once I took off the air pocketbook I looked effectually. I saw a little plastic insert where the wire is attached to (it has a pocket-size spring at the end). This had broken and would not stay in the pigsty to make a connection. Once I fixed that, the horn worked fine. Information technology is worth looking at it, it could be that simple.
You remove the air handbag by twisting a screwdriver in the back of the steering bike to unlock the servant. Promise this helps.

I thought it was the ground also but I moved the grounds and nonetheless only got audio out of i horn. I even made my ain harness for the other horn and put to a good ground and got aught.

Seems to me that if you're getting one horn to sound, and using the same method to power the other horn, and so the horn which does not sound must be bad.
Are yous going to go along using that push button bypass, or pursue fixing the switch side of the horn excursion, too? You lot'll demand to pull that airbag off and possibly the steering wheel too. A few months ago, mine wasn't triggering the relay due to a muddy slip band. Just had to be cleaned up a footling, and it worked again.

Seems to me that if you're getting ane horn to sound, and using the same method to ability the other horn, then the horn which does not audio must be bad.
Are you going to keep using that push bypass, or pursue fixing the switch side of the horn circuit, too? You'll need to pull that airbag off and maybe the steering wheel as well. A few months ago, mine wasn't triggering the relay due to a dirty slip ring. Merely had to exist cleaned upward a little, and it worked again.
I originally thought that the horn itself was bad until I plugged information technology into our 95 chevy and it made a noise. I am very hesitant to mess with the AIRBAG organisation. How do you go almost pulling it off? I know the middle, where you press, is a cover and also houses the airbag. But unsure and I practise not want to just start pulling on stuff. I exercise know to unhook the bombardment for at to the lowest degree 15 mins to let the memory reset on the airbag system and to pull the fuse(southward). I would similar to get rid of the bypassed push and get dorsum to the steering wheel choice. I am merely bypassing now to pass a state safety inspection for Missouri.
