  2. Parking Lamp // Headlight Issue

    General
    Hey gang, It's been a while since I've needed to post on here, but I'm sort of stuck. I'm not sure of the technical terms of everything, but I'll try to describe everything to my best ability. For a long time, when my low beam headlights are on, the orange light on the side doesn't light up...
  3. All rear lamps functional, but no brake light response...

    General
    2004 Trailblazer Just to summarize, I have confirmed all rear lamps work via hazards, reverse, turn signal, and remote entry flash. Both fuses involved are in tact. When I depress the brake pedal, I hear a relay under the console near the cigarette lighters, which leads me to believe the...
  4. A [Different] DRL Kill / Quad configuration - Is this possible?

    Exterior
    OK, So I have been doing a lot of reading and searching here lately about adding HID's to my 03 Envoy XL. I've got a pretty decent understanding of why I'd want to kill the DRL's etc so that the HIDs get full power and all of that stuff. I've been considering what options I would like best...

    Interior
    First I'd like to say hello. I'm from NY and I've recently acquired a 2007 Trailblazer LT with 32,XXX miles.

  7. 2005 Envoy air pump and relay

    OEM Issues
    I've read several posts on here and have a question that I can't find so be patient if you found it. :) On my 2005 envoy, I am trying to find the right/easy way to remove the air pump and relay. It looks like it may just be three screws that mount it to a plate on the frame, but don't want to...

    The 02-09 "How-To" and DIY Section
    My 02 Trailblazer LS lost low beams last week, right after jump starting a guy with my car running. High beams are good. I checked underhood low beam fuses 3+6, swapped relays 45+46 (even tried a new one) and checked all the fuses in driver side 2nd row underseat fuse block: 4, 7, 32, 40, 50...

  10. Projects that make you wonder what you got yourself into

    TrailBlazer / Envoy Chat
    I was wiring up a relay module for a project of mine on the Trailblazer (moving slowly due to weather!) and part way through as I was staring at it I wondered how smart I really was doing this :bonk: I hope I wired it right. Trying to keep all those wires straight and hoping I got them in...

  12. VVME HID's - Power?

    Exterior
    Just installed my VVME 55W HID's last night and everything is working correctly: high beams and low beams. The question I have is in regards to power: is it necessary to run a secondary power line from the battery with a relay on it? Right now i have them hooked up just through the ballasts...
