    I've thus far added a K&N filter in place of the stock one, the Bug Gaurd on the Hood, and rain shields for the windows.

    I'm currently retro fitting a cold air intake made from the stock filter box. Pics soon.

    For those who aren't already aware, there's multiple forums here for Envoy/TB/Bravada owners. It appears that this Parts/Accessories Forum does not have as many entries as the Envoy Parts/Accessories, so if you're looking for something that's not shown here, take a peek at one of the other boards listed. There are parts that are applicable for all three triplets on the Envoy Parts/Accessories board -- perhaps the HOSTS should consider making them all into a single site, like the main My 2002.... board.

  • I purchased a 2002 TrailBlazer LS about a month ago. I'd like to add to my TB a deluxe overhead console (typically found on the LT and LTZ models). Has anyone had any experience with this? If so, I'd like to learn what it will take to do this work myself. Thanks!
  • Does anyone know where I can get running boards for 2002 TB LS? Thanks
  • Go onto Yahoo.com and type in SUV Accessories. You will find a huge selection of places where you can get running boards and so much more.

    Have fun!!

    So far, I have a MagnaFlow 3" exhaust system, K&N air filter, Airaid throttle body spacer, a Lund wind deflector, Deflecta bug shield, Vent Visors, upped the tire size to 31's, and the best add on of all... Class 3 heavy duty trailer ball.. =) (nice chrome really stops those tailgaters.) BTW dont go 4x4ing w/ it, not high enough... =oP future mods include GoRhino Push bars, 1.75" laser cut spacers for a lift in front, full sound system, and another set of running boards.
  • what size rims and tires do you have now? I'm interested in changing my tire size too but I'm worried about how big I can go. Also, could you tell me more about these lifters for the front end as I'm looking into that as well. Any info would be appreciated.

    Anyone taken apart the headlights to add Xenon? Just wondering if you know how to take them apart. Looks to be all enclosed, not too easy to get at.

    there are large rubber caps on the back of the lamp housings that can be removed to access the lamps themselves.
  • m2icemanm2iceman Posts: 27
    I saw the rubber caps, werent sure if they are removable or not. Ill have to take another look and take them off. Thanks for the advise.

    i've already installed new bulbs in my 2002 trailblazer.first remove grill.it snaps out of place.first time it might be a little hard to do.then on the top of each headlight on the corners there is a lever which must be lifted up it's very tough the first time.then disconnect the lower outside plug that goes to the marker lights.you will be able to swing your headlight out a little.then remove your rubber backing that covers the bulbs.the bulbs turn out and turn back in. good luck!!

    right now, i have the stock 16" alloys, and I have the Toyo Open Country A/T 245/75/16 tires. you can also put 265/70/16's on it, but cant go any bigget w/out about a 2" wheel spacer or offset rims(highly unlikely to find in 6x5 bolt pattern) on the front, you have issues because of the camber setpoint. the spacers were quoted to me by a laser machining shop for stainless steel. they would charge me about 200 to set up the dimensions, programming, etc for the spacers, and probably about 75-100 ea for the spacers to get cut. trying to talk the local dealer into ordering multiple sets to reduce the price... =P but any machining shop should be able to do it, just make sure that there is a lip to hold the spring on like the shock. The best guesstimate for the spacing a concensus of 3 different off road shops. one said 1.25, 1.5, and 1.375 spacing. i took the larger to preserve the driveline angles, brake lines, etc. with the angle, it should raise the front about 1.75-2.00 inches. Should level the truck front to back. Theoretically, it may increase the way the vehicle handles, making it less front heavy and transferring some weight to the rear...
  • So far the setup you have including the spacer is exactly what I'm looking to do, But since this being a new car I'm a little spooked about trying something unproven. I know I'm bein paranoid. Let me know how everything goes on the suspension mod and maybe I can get my chicken self to try the same thing. Thanx for the info, very helpful :-D

    I'm looking into getting an upgrade to my sound system. Since the Bose wasn't in the model that I picked up, I decided to give it a trial and see what happened. Didn't like the sound, it was a bit muffled to me, so I'm going to get an upgrade at a local shop this week.
  • tblazer503tblazer503 Posts: 620
    good luck vgaines. As far as i know, the wiring harness is not available yet, and will not be for some time. It is a relocation kit for the OE stereo because the databus interface wire that runs through the connector is very tempermental. apparently, your onstar, and airbags go through your stereo connections. I would only go to a reputable shop for this. And ensure they use the correct wiring set-up. good luck!

    I hope I am in the right place! It sounds like I might add and learn here!

    Long Story!
    I had an aftermarket stereo system installed in my 2002 Trailblazer. At the time, the installing company told me that the vehicle would not "operate properly" with the factory stereo removed, so they charged me $85 for a wire harness so they could re-locate the factory stereo in the back cargo area, then installed the aftermarket stereo in the dash. I did loose things like door chimes and Onstar capability (which I never wanted anyway), since these things come through the factory sound system.
    Everything was fine, until somebody broke in and yanked the aftermarket unit out of the dash. In the process, they unhooked all of the wiring, so the factory unit was no longer "in the circuit". The vehicle appears to be working totally fine. I am driving it around with no stereo and so far I can't find anything that is not working. I tested the factory alarm, it works, the airbag light is not lit, etc. When I went back for an estimate, I showed the aftermarket installer that everything still worked, and he said that "the information they had said it shouldn't". I asked if they had some document so I could understand, but they didn't have anything. They quoted a new $85 harness for the repair install, but I don't really feel like paying it again if it is not needed. Anybody know the truth? The dealer doesn't know anything and didn't seem very interested in researching it for me. If anyone has info, please let me know!
    I personally think it is irresponsible for a manufacturer to link critical security and safety systems through a stereo system, knowing how many do-it-yourselfers install aftermarket stereos. It seems like a way to force you to buy their upgraded stereo! Isn't Microsoft in court right now for doing something like that?

    has anyone found a replacement shock for the 2002 trailblazer? my 2 wd/LT rocks and rolls down the highway.
  • tblazer503tblazer503 Posts: 620
    rem038, no, havent found any new replacements yet. The main reason that I can find is that GM hasnt released the specs or no one has finished r&d on them yet. Have heard a rumor that all Bilstein shocks(OE) can be revalved to custom specs. I plan to look into this, but currently can't find anyone who does this yet. If you want to stiffen the ride a little, I have had a shop recommend putting "air bags" inside the rear coils to stiffen them up, but without new shocks, it probably will make the ride much more bouncy because the shocks will still be weak(IMO) and the springs will be stiff. hope this helps some, if i do find some, i will post it.
  • vgainesvgaines Posts: 5
    I think I'll just stick with what I have. It gives me a pretty decent sound, so until I am just THAT unsatisfied with it, it's "factory" for me.

    It does sound muffled, at times, but I think I had the bass turned up a little too high, and it drowned out the treble.

    I wonder what kind of speakers are installed?

    Think I could just have new speakers installed without the extras?
  • sildogsildog Posts: 50
    I just bot my 02 TB back from aftermarket stereo installation. It turns out it did not require relocation of the factory unit, so it was a simple swap of the head unit. The only complication is that the factory unit does not power up with ignition, so you have to run an ignition wire up there to power it up.

    I tried using the factory head unit with aftermarket speakers. The sound was much improved. The concern is that the factory speakers are high impedance-usually 16 ohm. Aftermarket speakers are usually 4 ohm. A 4 ohm speaker will draw a lot more current from the amp than the 16 ohm. I was trying this combination with the factory radio not in the dash and it got very hot during about 10 minutes of sustained listening-almost too hot to touch the box. Of course, I have no way of knowing how hot it would be with factory speakers.

    I would like to add fog lights to My Trailblazer LS. The other two TB models have them stock so I would hope GM would have a dealer installed accessory kit for this upgrade. Is there one? Has anybody here done it? How much? Thanks in advance.
  • tblazer503tblazer503 Posts: 620
    Yes, I have priced the kit from GM. The OE wiring harness is ~$600 the OE fog lights are ~150ea and the OE switch fascia is is ~$50 w/ new switch. Not exactly worth it considering still need labor for install. Better going with PIAA or other fog light kits. Hope this helps.
  • mjdartmjdart Posts: 11
    tblazer503, $1000 for a pair of fog lights! Do they actually sell any?
  • tblazer503tblazer503 Posts: 620
    probably not, mainly for accident replacement I would imagine. Just as an FYI, that was also with a 20% "preferred customer" discount(whatever that means) Personally, I am bearing with my 07/01 build LS for now, and later, plan to upgrade to a LT or even Envoy or Denali(dreaming) I figured by 4th qtr '04 I will trade in and hopefully all the bugs will be worked out(engine, computer, and maybe even a normally mounted seatbelt) Just my plan, so far my truck has been in for 3 Recalls, so I don't plan to keep it past the warranty. =o) just my $.02 hope this helps
  • I also want the fogs for my LS for driving at night in rain and snow but have seen some after markets in the areas where they go for the LT and LTZ. Not impressed by having to cut out the grills. Has anyone put aftermarket fog lights on in the gaps on either side of the license plate holder in the front bumper? Would this restrict air flow or would the wires get too hot by the radiator?
  • Just talked to the guy today about a TB he did a lift on. He has a 3 inch body lift fabricated from a full size Blazer kit. The suspension is modified using the original front struts. he modified the mounting points. He says if I was interested all I have to do is send him a set of factory struts and He'll do the fabricating and send em back to me for around $300.00. He said, 3inch is the limit for raising the front end . Anything more then that would be an invitation for binding problems. Oh, and its on a 4WD. If anyones interested call John Wargo at Customshop (815)796-2772. He's a pretty nice guy too so dont hesitate to ask any questions.

    If your looking to get stock chrome rims, check this site out. I talked to them and Im in the process of getting them for the wifes 02 Altima. I was told you can order them for the Trailblazer. The cost is apporx $500-600, that includes shipping (You pay both ways $70 each way) and about $400 for the rims. They are triple plated chrome. Ill send a message on Monday after I recieve the ones for the Altima and let you know what the quality is like. Anyway, just a guestion it your looking to add chromes and not pay too much.

    FYI:
    You pay, they ship them to you, you exchange them for your stock rims and send the stocks back to them. They can get the 16" and 17".
  • I'm thinking of buying a new Trailblazer. I've heard there are 3 different after-market Nav. systems available for the Trailblazer. Has anyone had any experience with them--one is Audiovox, one is from Alpine--can't remember the third?
