Hence, while silencing the horn, you may be eliminating another accessory/feature. Cheers.One problem with removing the fuse for the horn is that this same fuse may also be on the same circuit for another electrical component.
Should get power constant on one term, and the other two should light when the horn button is pushed.
Test all sides of the relay with your light. Follow the sound to find it if you hear it. If you hear this, then the switch is working, but the relay might not be. If you listen carfully while pushing the horn, you should hear the relay faint clicking. Also could be a horn relay if it has one. Does it have an after market steering wheel? Because aftermarket wheels often have crappy horn switches in them. If you try all the wires and none make the light blink, then its probably a problem with the horn switch in the s. The horn switch is the wire that makes the light blink when you push the button. Put the test light clip on +power, then check the wires on the collumn side one by one, pushing the horn button on each one. I would start with the wiring harness where the steering collumn plugs in and decipher which wire is the horn wire. If everything else is working fine, then to troubleshoot you'll need a testlight. Probably the switch in the steering wheel, or fuse, but usually horn fuse works other things too such as cig lighter or radio. Let me know if you require any further assisance. I have made you a wire diagram to help assist you, but it is only for a referencre and the wire colors might not match, so be sure that you actually test the wires to find the actual wire for the horn. The rest is simple, you just connect one of the wires from the Horn Button to the cut wire from the turn signal wire connector, and then connect the other wire from the Horn Button to a good ground, and then test the operation of the Horn Button, and if the horn is working with the new Horn Button then mount the Horn Button where you want it to be and the job is complete, and you should then have a fully functional horn again. (or at least enough to connect a wire to the cut Horn wire from the turn signal wire connector) Once you have successfully located the Horn wire, then on the wire connector from the turn signal switch, cut the horn wire about three inches from the wire connector for the turn signal switch. (make contact for only a second and do not ground the wires that you are testing for more than a second or you could blow a fuse) You can connect a test wire to a good ground and quickly make contact with the wire that you are testing and when the Horn sounds then you have found the right wire. However that is not always the case, and the wires should be tested to be certain of the Horn wire. Then locate the Horn wire, it will have battery voltage at the wire and when the horn wire is grounded the Horn will operate or sound, and usually GM used a Black wire with an Orange stripe for the Horn wire at the vehicle wire connector for the turn signal switch from the vehicle wire harness, and the wire usually changed to a solid Black wire on the wire connector from the turn signal switch. You will also need enough ground wire to wire the horn button into your vehicle, and most likely a few wire connectors, and that can all be figured out once you actually see the Horn Button that you purchase.įirst locate the turn signal switch wire connector and it should be on the lower right side of the steering column.
PUSH BUTTON CITY HORN INSTALL
You can by-pass the horn pad on the steering wheel and install an after-market Horn Button to operate the horn, and you can purchase an after-market Horn Button from most auto part stores for under five dollars, and there are a few different designs that you can choose from. Connect the auto switch wire (the one that reads 12 vdc when the horn button is pressed) to the remaining horn wire. Or, connected to a black horn wire if both horn wires are isolated from the bracket. The auto ground wire(s) are connected to a horn wire that is common with the horn bracket. I would expect one of the wires will also be zero ohms (ohmmeter) when measured to the car frame or body. The value should be zero before pressing the horn button, and 12 vdc when the horn button is pressed. Now, using the voltmeter, measure the voltage between each wire (from one wire to another). This means the horn coil is not grounded to the bracket. The value between each wire and the bracket should be very high (10 kilohms or more). The value between the wires should be low (10-100 ohms) but not zero. Do you have a multimeter? Using the ohm-meter, measure the ohm value between the two wires, and from each wire to the horn mounting bracket (you need contact with un-painted metal. I am not an expert on auto horns, but can solve most electrical problems.
