  1. LED Headlight Bulb Fitment

    So I have a 2006 GMC Envoy XL that I want to out brighter headlights in. I want to use the bulbs from Lasfit because they are a great option for the money, but I’m worried about the fitment of the bulb in the headlight.

  2. Issues with 2006 Trailblazer Intermittent Wipers

    The 02-09 "How-To" and DIY Section
    I've got a 2006 Trailblazer and the intermittent wipers aren't working properly. The delay settings aren't in the same position anymore and almost every time the wipers are turned on the spray goes off for a few seconds. I'm thinking it's a short in the windshield wiper switch. Should that...

  4. Trim codes information request

    The "How-To" and DIY Section
    Howdy all, I have a 2006 Trailblazer LT, and need to replace the front passenger door panel trim. There are a bunch of places that sell them. GM, of course. But the cost is a little more than I would prefer. I don't mind getting a clean used one. The problem I am thinking of is getting the...
  5. Color codes for interior?

    Howdy folks. I apologize for the possible repeated question, as I didn't see this issue addressed. The front passenger side door panel has broken off. The previous owner wasn't terribly kind to it, and even tried using a self-tapping screw to keep it in place. I would like to order a...

    I have a 2006 Envoy and I was stuck in "4WD" but only the front differential was locked and my transfer case was in 2WD.

  8. [SOLVED] 2002-2005 Alternator on a 2006 Trailblazer 4.2 LS

    The "How-To" and DIY Section
    I can't really seem to get a fix on why a 2005 Alternator can't be fit on a 2006 Trailblazer 4.2L LS. Is it the amps? The bracket? The connector? 2006 Trailblazer is out on an Island as the 2007-09 also do not retro. I want to fit one of those HO Alts but most only go to 2005.

  12. Lining up a AC mode actuator

    I decided to start a new thread on this subject as all the other treads were very old and did not answer the question on how to actually line up the ac mode actuator.

    Hi, Knowing nothing about stereo systems, I recently decided to upgrade my back speakers since one blew out. I bought some Alpine Type-R SPR-17S, but then i was reading that you shouldn't put component in the rear. So rather if i have to put them infront i'm still left with no back speakers, so...
