SOURCE: HOW DO YOU FIX A HORN THAT GOES OUT ON A 2003

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.

What is the fix for my 2003 Chevy Tahoe with the gauges not working till I pull the pic/dic fuse and then put it back in.


IS this a one time issue? IF so when the battery dies and is jump started, the voltages can be spiked or sag and this causes issues with the electronics in the boards. When you pull the fuse and put it back you are resetting it and not letting drop or sag or spikes happen. If the issue keeps happening then you need to look at for issues with bad connections on the boards or the BCM

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.
