  1. HDM/Broken Fuse Block

    OEM Issues
    I've been troubleshooting my 2005 Trailblazer 4.2 I6 Low Beam issue. Great threads by the way! Long story short. I have no Battery 12V to pin 2 on the HDM. If I run battery 12V to pin 4 I still have no low beams. However, if I run 12V to either low beam fuses I get low beams on left and right...

  3. Fuse box picture request

    2007 Chevy Trailblazer 4.2 I6 4x4 This may seem like an odd request but I need to find out the set up for a fuse box.

  4. 2004 Envoy

    My wife left the radio and DVD player on while waiting for the kids to get out of school yesterday, and killed the battery.

  9. Major Envoy Fuse Problem

    OEM Issues
    My stupid friend jumped his truck off my 2002 Envoy and hooked up the cables to my fuse box under the hood rather then the battery. Now the majority of the things that are in the rear fuse panel don't work (radio, heat, auto seats, rear defrost) - the only thing I can tell that works for sure...
