The fuse would be the best place to start.

The button on you steering wheel is the problem, try to open it up and pull the spring just a little bit. I think you have used it too much ;)

I just purchased my Tahoe, and the horn stopped working and I have also been a bit concerened as to whether the temp is kinda high because it's reading right below the 210 mark and a local parts house told...


the temp is fine 186 would be too cool for this engine. as far as the horn it could be the horn contact in steering wheel a relay,blown fuse, bad hoern. the relay and fuse for horn are underhood in the power distribution box. it will have a diagram on inside of cover check the fuse if it is good. hold your hand on relay while someone pushes horn if it clicks relay and contact are good and it is horn itself. if no click swap relay with another like it in box still no click probably the contact in wheel.

HOW DO YOU FIX A HORN THAT GOES OUT ON A 2003 TAHOE


This is a challenging repair but you can do it yourself if you are comfortable with the following instructions. For tools, you will need a voltmeter, a set of allen wrench screw drivers and a set of wrenches. The horn on a Chevy Tahoe operates with the use of a relay. This means that the power for the horn is received from the fuse block under the hood. Power from the fuse block runs to the horn relay. The commonly open end of the wire goes to the horn. The horn is then grounded to the frame. Power to the activating terminal of the relay comes from the Body Ride Control or from the accessory side of the ignition switch. The negative side of the relay runs through the column to the clockspring. The clockspring is also used for the air bag system. The wire then continues to the steering wheel air bag where it is attached. As the air bag is pressed, it causes the wire to ground, actuating the relay which, in turn, activates the horn.

I have a 2002 chevy tahoe and my horn doesn't work. I was wondering where the fuse box is located in my vehicle and which fuse goes to the horn (so I can check if its blown).


Go to the wiring on the horn andd run it back to the fuse box. Replace the fuse or "hot wire" system and see if the horn works. It is also possible to ware out the horn by constantly reminding drivers how poor their driving is. I use to sell for a living and drove 60,000miles per year. I burned my horn out 2 times. Good luck

2000 Tahoe Horn broken


You can remove the horn relay and use a Ohm meter and check the resistance between the horn relay connector terminal No. 86 (Black Wire) and ground. If the ohms are less then 5 ohms replace the horn relay. There are a lot more tests but as Polarcycle states you can do what he suggested other then I believe you have two horns in this vehicle.
