    Hello there! I just bought an 2004 Chevy Trailblazer LT in December of 2020. The previous owner had replaced the 194 bulbs with LEDs. Well some of the bulbs have started to flash and some have even gone out. I am curious to how many bulbs in/on the car are actually a 194. Is there any that need...
  2. Air Induction
    Hello, new to this forum but it looks fairly active and maybe someone can help. I recently decided to spend money upgrading my 2008 Trailblazer LT, and I bought a K and N air intake and throttle body spacer. I put both in with some help from a friend, but now my check engine light won’t go away...

    2005 Envoy SLT. My driver's side reverse light went out. I went to put a new bulb in and when I removed the old bulb I noticed a ton of rust/corrosion in the socket. Its beyond repair. The socket is toast. I looked a bit online this morning but was unable to find an aftermarket replacement...
  5. The "How-To" and DIY Section
    I have researched it up, and I've found several accounts of what it could be. The most common that seems to be popping up is the throttle body is dirty needs to be cleaned. But there is another one with a coil? I have attempted to research how to fix that, but I cannot find anything about it...

    Hey guys, I saw a lot of poor videos (no speaking, dark, too long, etc) on how to replace the headlights on a trailblazer, so I made my own. I tried to be concise and make it so anyone who wants to do this job can follow my video and get it done. Let me know what you think...

    I have an 04 TB LT, and for awhile now the Airbag and ABS light have been coming on. They always go on and go off together. Sometimes it does it and other times it doesn't. They've both been on now for a few days. I was driving home in 4x4 Hi because of the bad snowy road conditions and...

    I got the Recon Big Rig Running Lights for Christmas and now I have them installed. They look much better in person. They came with 10-minute installation instructions, but this install took several hours. I had to remove the running boards to put the screws in and removed to whole front...

    I couldn't find a good how-to for fixing the climate control light, so I took some pic's when I replaced mine. Here's how I did it: Remove the climate control module from the car. See other threads here on how to remove the dash. Remove the 2 screws on the white tabs that hold the unit in the...

    My change oil light button came on 2 1/2 weeks ago. And I haven't changed my oil yet. Out of no where, my reduced engine power light came on right as I pulled into my garage. Then I turned off my tb and re-started it. Then the check engine light and the reduced engine power button lit up...

    I was stupid, and while changing out the interior lights that come on automatically when the door is opened, I got a spark and poof! They no longer work. Everything else works, in fact I can push the light to toggle it and it still work, but nothing when I open the door or unlock/lock the...
