    I have a 2001 DC 4X4 and am having trouble keeping my horn working. everytime I change the fuse and push the horn - it blows the fuse. Obviously, there is a short somewhere. Any likely spots I should check first for an easy fix? Anything else that can cause this issue?

    Thanks:confused:

    :) You can try an isolate your short in your wiring that is causing your fuses to blow. Go under the hood and unplug your horn or horns and replace your fuse. Then push the horn button and see if the fuse blows. If the fuse blows, then your problem is in your horn button or the ground or the wires to the horn .
    If the fuse does not blow, then plug one horn, if you have two, or the one and see if it blows the fuse. If the fuse blows, then the horn could be stuck and is grounding out. If you have the two horns system and the first horn did not blow the fuse, unplug the first horn and plug in the second to see if that horn blows the fuse. Good Luck.

    Instead of wasting 10 fuses trying to find it, just go buy a circuit breaker that is the correct size. It will work the same, but you wont have to keep reaching down to replace the fuse, just wait til it cools off and closes the circuit again. I agree with what was said about disconnecting both horns and then connecting them to see when it pops.

    Thanks guys. I only see one horn, but I will look closer. I will unplug what I find and go from there. Thanks again.

    Pretty simple circuit, but the horn might be hard to get at, behind the bumper.

    Remove the connector from the horn, and try it. If the fuse still blows, then its not the horn, likely a short in the harness between the horn and the relay.
