I was just wonderin if any has had a problem like I'm havin. My horns aren't workin. The relay is good and I replaced the horns and they still don't work. If someone could help me out I'd appreciate it.

 

There's only a few things it could be, switch, relay, wiring, fuse, and horn itself (I don't think the horn circuit goes through the computer yet).<br>The way I'd do it is as follows:<br>1. Unhook the wire from the horn and attach a test light to the end of the wire. Press the horn button on the steering wheel and see if the test light lights up. Check horn ground by running a hot jumper wire directly from the battery to the horn. Do this for just a second because the horn draws a lot of amps. If the horn doesn't work, your horn is bad or has a bad ground. Verify the ground and repeat. If the horn works, proceed to step 2.<br><br>2. Probe the output of the horn relay, with the horn still disconnected, and see where the hot leads are. You should have one lead hot all the time. Two more should be hot when the horn button is pressed. The only way to distinguish which one is the relay output (differentiated from the horn switch input), is to disconnect the relay and press the horn switch, which will make one of the wires hot. If you do not have one all-the-time hot wire at the relay, check for the relay fuse to be burnt out. If you do not have two that get hot when the horn switch is pressed, disconnect the relay to determine which wire is from the switch. If the relay output wire never gets hot, your relay is bad. If you have hot everywhere you are supposed to, begin following the wiring to the horn from the relay as there is a problem in the wiring. If the relay input wire never gets hot continue to step 3.<br><br>3. We now need to verify the power from the switch. Before pulling the steering wheel apart, let's check fuses again, this time for the horn switch. This may not be obvious so just verify all fuses, inside the truck and under the hood, are good. Once all fuses are verified OK, pull the cover off the steering wheel and checl the horn switch. You should have a hot-all-the-time wire going to the switch. If not, and the fuses are good, look for bad wiring between the swtich and the fuse panel. If the hot-all-the-time is working, check the switch output itself by actuating the switch and checking the output with a test light. If the switch output is no-existent, replace the switch. If the switch works then trace the wiring between the horn switch and horn relay to find the bad wiring.<br><br><br>Hope this gets you though it.<br><br>Chris
