    Well my brake lights quit working the other day. I have gone through and found a bad fuse. SO I replace the fuse and the brake lights work. So then I try the hazards, and the fuse blows.
    So everytime I hit the hazards the fuse blows, but the fuse is fine when I use the brakelights.

    I am also getting a very similar problem with my driver side turn signal. Everytime I use the right(passenger side) signal, that fuse is fine. But when I click over to the driverside signal, the turnsignal fuse blows.

    I have tried several thing. At first the turn signal fuse wouldn't blow, the flasher module would just make a funky ticking sound when trying to use the driver side signal. I changed the flasher mod and found a bare wire in the rear, now it is blowing the fuse, rather than just trying to activate the flasher and the flasher not responding right.

    I assume that these problems are somehow related, being that the hazards use the same wiring as the turnsignals.
    Anyone have a similar problem or have any suggestions?

    Thanks

    Sounds like you have a short circuit somewhere between your steering column and fuse box. Start out by finding a wiring diagram and figuring out what colors go to your brakes and turn signals. Then start pulling stuff apart under you dash and steering column until you find a shorted out wire. On second thought, you may want to start at the rear of the K5 and work your way forward. I just replaced the wiring under my dash because a short circuit and it never blew a fuse. Of course, my wiring is a lot more simple.

    Mud is just thick water, or is it that water is just thin mud?

    I think I figured it out. When I put my Custom front bumper on I had to move the turn signal up, behind the grille. I used Semi trailer light and they had to be grounded at the mounting points. I pulled the driver side one off and found that when I mounted it last time, I had pinched a wire and it was grounding out.
    I also found a bare wire in the rear by the frame rail, so I fixed that also.
    Now I will just have to wait and see if I have found them all.

    Thanks to everyone!

    You know what, if it is not too much trouble, the diagram may come in handy down the road.

    If it is not too much trouble I would appreciate if you e-mailed it to me.
