    my 2004 trailblazer was in an accident where the right front headlight and bracket were replaced. after the repair work, the headlight giggles/flickers when driving down the road. the repair shop could not determine why it still giggles, and looking at the assembly, it all looks to be in-tact. But if I bounce my hand off the headlight or bumper, the light giggles. Its a bit annoying during night time driving. any recommendations/suggestions.

  • wow guys this prob is driving me insane

    i bought an HID kit thats fully genuine. the first time i installed it in my 2008 trailblazer ltz the lights just disconnected unknowingly. i checked both fuses for the high and low beams(HIDs on the low beams btw), and theyre both good. my assumption was that the IC turned them off as a trouble code. i took it to the dealer and they fixed it on warranty. Now i got no warranty and i redid the same moistake and they still disconnected. simply i wanna put the old ones bak now, any light how to reset the IC or fix the prob????
  • I have had 2 occasions where my headlights went off while I was driving at night. I saw a similar problem reported with a 2003 Trailblazer, but the driver indicated that 'high beams' worked, thought the low beams were OUT.

    I did not try high beams when I lost my headlights, so I don't know if my problem is the same as the 2003 TB.

    Has anyone else seen this problem on a 2002 Trailblazer? What was your resolution?

    Thanks...Pat
  • I have a 03 trailblazer and lately i have noticed them dimming and returning to normal. Did that happen to you before they started going out? I thought i was crazy!

    thanks

  • I didn't NOTICE notice any dimming, but I couldn't swear it didn't happen. The lights went from perfectly bright to totally dark in a blink of the eye. It might be worth checking out before you get out on the road and lose your lights entirely.

    I wish I'd had the presence of mind to call On-Star when the headlights went out. They can sometimes run a remote diagnostic on the vehicle and it would have been nice to get a diagnostic run when the problem was actually occurring.

    I took the T'Blazer in for service, and they could not duplicate the problem, but replaced a headlamp relay or something similar. I couldn't risk going on the road at night with the possibility of this happening again.

    I have had several occasions where the headlights on my 2002 Trailblazer went out. It was pretty scarry when it happened late at night on the freeway with a lot of traffic around. I was able to turn the switch off and back on and they came on again but it did not work the next time. They just came back on by themselves. I will have to limit my night driving.

    I have also noticed a clicking noise in the dash area by the steering column and I don't know if this is related. It usually only happens when I start the car.

    I hope someone posts a solution to this problem.
  • That happened to me just a few nights ago in my 2002 Trailblazer EXT. I keep the switch on automatic so that the headlights come on when it's dark. Well, it was pitch black outside and as I was driving, the headlights went off completely!! I immediately tried the high beams and they came on. I turned the headlight switch to manual, but they still did not come on, so I left the high beams on. Right before we got to the restaurant, the lights started working. Then when we left, the same thing happened,at first the lights were fine, then they went out and the high beams worked. So, I called the local Chevy service dept today and the service manager said it sounded like the multifunction switch and it would probably cost about $300. I don't know if that's with labor or not. So, I've been searching the Internet for more info. If anyone has anymore info, please send it my way!! Thanks!!

    Our 2002 does the same thing. Did you find a solution to this??? Sounds like we are not alone and it happens to newer models.
  • I actually thought it was my imagination. I live in the country so it is not until i drive on the back roads that i notice it. So for about three months i thought it was me, but now that i started reading all of these messages did i realize it is not me and i have to take it to the shop. My four wheel drive has also broken 3 times, not the power drive but the relay that allows it to go to 4wd. So when it goes in for one it will go in for both. I will absolutely turn the button to on instead of the automatic on. I also drive with my fog lights on just in case.
    thank you for responding

    Did you ever find out the cause...ours does this all the time and we have to drive with the brights on until it stops.

    I have an 02 Trailblazer and the headlamps went out last night. I have no idea what that is about haven't had time to check on it. But I do know that the clicking you are hearing is probably the one of the Sylinoid switches for the A/C -Heating ducts. They are electric and sometimes start to stick. When you start the car they will make repeated clicks and they do sound like they are coming from the steering column area. Dealer fixed mine cost about $150.00.

    If you find anything on the headlights let me know.
  • did you get your headlamps to work? let me know what was wrong... rcaston19@aol.com
  • did you find a fix??

    In Nov. '08 my driver's side headlight bulb went out. Upon checking, the socket/clip for the bulb was fried. Had to replace the entire headlight system. Luckily I found a used one at the local junk yard. Now 3 months later, Feb. '09, my passenger side did the exact same thing. Clip/socket is fried and need to replace the entire headlight again. Is anyone else experiencing the same problem??

    Have a 2003 Trailblazer and have replaced low beam bulbs on each side numerous times, seems like every 3 - 4 months. Found the socket that plugs to the bulb burnt and one had shorted. Advance Auto offered a replacement socket which required cutting off the factory socket and soldering on the new one. Today I had to replace another bulb and I found one of the replacement sockets also burnt. Not sure what is causing this type of failure, but isn't good!

    A long time ago I replaced the sockets with ceramic ones. Heat is the culprit.
  • Burdawg - Where do you get the ceramic sockets? -Thanks!
  • burdawgburdawg Posts: 1,524
    Either Pep Boys or Autozone, I don't remember.

    I had the same issue. As I replaced the bulbs several times at a Napa parts store Then they told me to see a mechanic near-by for the solution. Answer: chevy makes the wiring harnes's too small to supply the voltage needed. Mechanic sold me a Delpi wiring harness ($30.0) to attach to the bulb socket. 8 months have passed with no issues. I hope this helps.

    My headlights bulbs didn't actually burn out, they just went off by themselves! I have the sensor where they come on automatically. It just happened again a few weeks ago and I had to pull over, stop the motor, then start it again. Thank God they came back on. I am puzzled and don't want to spend a lot to get it fixed! Like I said before, the service manager at our local dealership said that it sounded like the relay switch which is costly to replace. But he didn't know for sure. Did your bulbs actually burn out? Or did you have the same trouble I have had?

    '06 pre-owned certified,4.2L.Lights vibrate at nite,dealer re-positioned headlight locks.Still shake.Grill originally seemed loose,but not since dealer "fixed". Any thoughts?

    Our daughter's 2002 Chevy Trailblazer headlights went out abruptly the other night and would not come back on. After reading your post, I walked out to her car and did what you suggested, swapping the #46 fuse with the #45. My husband's jaw dropped when that solved the problem...he promptly went to Auto Zone and bought a replacement fuse for under forty bucks. We had discussed taking the car to the dealer, but your suggestion saved us the time and money. Thank you so much!

    Lights vibrate at nite...

    Do you mean that you can see the light beams move (on pavement or whatever) or do you mean you can hear sound emanating from the lightbulbs?

    on green interstate signs,low signs along hiway.

    It could be that the screws used to adjust the headlamp position are broken.

  • how did you replace the socket? i have a new socket for my 02 trailblazer. i know how to get the lighting assembly disattached from the car, but when i removed the cap, i couldn't figure out where to wire the socket. do i just strip the wires and rewire the new one on, or do i need to take more of the car apart?
  • My 02 TrailBlazer "Service Engine Soon" light is on more than it is off. Diagnostic hook-up says it needs a Cam Sensor.

    Now about 3 different times I have drove it at night the Low Beams shut off by theirselves and turned dial switch from automatic to manual does NOT work....have to drive home on Brights....after a few miles I can go back to low beams, but they will go out again after a few miles!

    The cruise will only work a few times a month, also.

    SO....since the high beam switch and cruise are all on the same lever on the column, are those issues related, or is the cruise messing up due to the cam sensor which makes my TB want to die at stops at times????

    Any ideas here? Called Chevrolet today and they can find NO recalls on any of this and the local dealer says just to find the problem is $34/hour at about 2-6 hours.

    Ummmm.....gouging!??!?!

    I just had the same thing happen to me. I own a 2003 Chevy Trailblazer and my low beam head lights went out. I swapped the #45 & #46 Relays. It worked fine this morning, but when I went out for lunch my running lights don't come on any more. For the moment I can turn on my low beams but the running lights don't come on. Can anyone help. What is a permenant fix for the low beam lights going completly out? I call the Chevy Dealer yesterday and they want $98 bucks just to tell me what is wrong with it. I don't think so. :confuse: :lemon: :sick:
  • 2004 Trailblazer low beams not working (kept going out but would come back on) changed the #45 and #46 relays and lights started working. Will be picking up new relay tommorrow. Thanks!
