GMC Envoy Headlight Problems

I bought a used 07 Envoy. The headlights are out of wack. How do I align them? I saw that the light compartments have two small tabs that you pull up to release the headlight compartment, but I didn't want to mess with it.

    I have a 2005 GMC Envoy and my headlights have quit working, well at least the low beams (both sides at the same time). I have checked the fuses and the bulbs and both are fine. What else can I check before giving up and landing at the mercy of a local auto shop? I am not exactly a mechanical girl, so feel free to speak in short words.

    I am having the same problem. I even went ahead and changed the headlamp switch...no luck!
  • I have a 2004 Envoy SLT and have recently been experiencing a problem with the automatic headlights. They will not turn on even when it is completely dark. If we turn the car off and let it sit for an amount of time they will come on when we restart it. Does anyone know why this is happening or have any ideas on how to fix it? We are the second owners and have already had to replace the control panel module because it was causing the instrument panel to go crazy, lights blinking, guages not working, etc. The Fog lights work, and the high beams work when the knob is turned to "on", but not on automatic. It's almost like the sensor is not sensing that it is dark outside. Can anyone help?
  • I have a 2004 envoy xuv and i have noticed that when i use the power windows my volts gauge goes down slightly and my dash lights as well as my headlights dim a little. i tested the battery and i replaced it and then i tested the alternator and it is putting out 14.45 volts. what else can it be? please help!
  • I have a 2004 Envoy SLT and three times in the past year the headlights have gone off at night while driving. The manual switch will not turn them on. Only the emergency flashers will work. After stopping the car and waiting a few minutes will the lights work again. This can be a dangerous condition and I am hoping someone might have a fix for me. Thanks.
  • I have a 2004 GMC Envoy and had the same problem. What worked for me was changing the headlight fuse. No more problems. Tip: the fuse is the same one for the fan...found that out by accident, but it solved my problem. Only problem i've had since i purchased the Envoy. ;)
  • i've noticed this also and looking forward to the responses. I have a 2004 GMC Envoy. :confuse:
  • Unfortunatly the issue is present on all these vehicles. Many new customers have reported flicker, flash or even off issues. GM has a "confidential internal" bulletin for this issue. Just make sure cables and battery connections are clean and tight, if alt and battery check out ok issue was built in and no fix is available.
  • i have a envoydenali xl 2006..have no lowbeam lights. checked bulbs-good,fuses-good,installed new high beam low beam control on colum-nothing changed. any ideas to what i can check...
  • PROBLEM SOLVED-relay#46 in fuse box,usage headlamp driver module-----swapped with #45cooling fan relay just to check.....IT WORKS...heading to auto parts to buy new one.....thanks everyone :) :shades: :D
  • Is there a cheaper replacement for a HID headlight on a 1999 Envoy bulb rather than pay the GM replacement price? We're talking close to $1000 or more for the bulb and ballast... Can I replace the system with an after market kit? Thanks!

    Thanks rrobar. I had the same problem with my 2006 Envoy, and did what you suggested - swapped the #45 relay into the #46 spot to check - and my headlights worked with the #45 to verify my #46 relay was bad. I called around and none of the major auto parts retailers had it in stock, so I had to spend about $45 at a dealer for the part.
  • One of my HID Headlights went out-cost $ 1300.00 to fix the one headlight. Anybody know of a cheaper solution, wether it be convert the HID HEADLIGHTS to STANDARD HEADLIGHTS., etc. Sure could use some HELP with this!!!

    $1300.00 to fix the one headlight

    $1300 seems way overboard. You can get a replacement bulb far cheaper than that at an auto parts store. What exactly did they do for $1300?

  • Yep, Thats Right- $1300 to fix the low beam headlight on one side. $650 for the BALLAST & $648 for the IGNITOR. I wish I COULD just slap a standard blub into it but they are HID headlights produced by GM. I would have never bought the car if I knew that there was this possibility of this happening. Thats why I'm seeking
    help ONLINE for a cheaper cure, would like to convert both headlights to STANDARD HEADLIGHTS. So far I don't know if its possible. The dealer can't give me a answer, they dont know for sure!!!!

    I don't know for certain what the answer is to your question but I notice there are a lot of kits on the market for converting standard headlights to HID. It would stand to reason that the reverse process should be possible and feasible.

  • As of Yet, after extensive searching, can not find a thing regarding converting HID headlights on a 1999 Envoy to Standard Headlights. If you run across something, it would should be appreciated if you would pass it along to me. Thanks
  • I am in the same boat with a 2000 Jimmy Diamond edition and yes you can. What you need to do is get the bulb retainer off of a standard headlight assy. (Bulb 9006) unplug the ballast assy. from the wiring harness and plug the harness into the 9006 bulb and install the bulb into the bulb retainer you just installed in the headlight assy. (I would get the retainer out of a junkyard for cheap) The harness that plugs into the Ballast is the connector for the 9006 bulb. The bulb retainer will screw to the headlight assy at the same locations as the HID bulb Security Torx screws. You might want to pick up some #10 screws and replace the security Torx fasteners. The ballest is behind each headllight assy. You most likely will have to remove the bumper cover to access the ballast resistor. You can get the security Torx bits at Harbor Freight if you need them.

    I have a 1999 GMC Envoy with HID low beam headlights. One of the headlights went out and I was quoted the following “replace the Igniter which costs $657.00 per side and also the Ballast which costs $616.00 per side. Or you could do the Headlamp Assembly which is around $1,000 per side.” I thought there had to be a more cost effective way to replace the headlight. Both $1,273 and $1,000 was too much for one low beam replacement. Especially when replacing two headlights cost more than the entire trade in value of the vehicle
    Using the limited information on the internet I was able to convert the HID headlights to standard 9006 bulbs.
    - I unplugged the wiring harness from the ballast that is mounted within/behind the bumper. I was able to unplug the harness without removing the ballast.
    - I tested the harness to ensure with a voltage tester to ensure the harness connector was 12.8v +/-.
    - The harness connects directly to a 9006 headlight. I bought one for $10 to ensure the appropriate fit and operation.
    - The original headlight assemblies (GM 16525606 / GM 16525605) do not allow for a direct connection with a 9006 bulb.
    - After talking to AutoZone and Advance Auto I got a quote for new headlight assemblies (GM2503174 and GM2502174) that would fit at $273 each. Though the bulb would connect to the new assembly - again, too much money. They advised they did not know of an “adaptor” that could mount to the existing assembly and accept the 9006 bulb.
    - Through Amazon.com I found Vehicle Interior Parts. They have a storefront on Amazon. I ordered the following from them –
    o 1998-2001 GMC S-15 Jimmy Left Side Front Only Headlamp HeadLight W/O FOG LAMP,LEFT HAND replaces OEM 16526227 Hollander 114-535L Partslink GM2502174
    o 1998-2001 GMC S-15 Jimmy Right Side Front Only Headlamp HeadLight W/O FOG LAMP,RIGHT HAND replaces OEM 16526228 Hollander 114-535R Partslink GM2503174
    o Total cost including shipping for both New assemblies was $84.00 - they arrived few days later via UPS packaged well and in new condition.
    o Each assembly included the high and low bulbs already.
    - I was unable to remove the existing ballast from behind the bumper. I was uncomfortable removing the body/bumper panels to gain access to remove the bumper itself. Therefore I zip tied the existing HID behind/next to the assembly location.
    - I removed the existing assemblies, installed the bulbs and connectors into the new assemblies and then installed the new assemblies.
    - The wiring harness on the driver side barely had enough length to plug into the slightly different bulb locations in the new assembly. I managed to manipulate the harness enough to get it installed though.

    I have a 2004 GMC Envoy. Both low-beam hightlights went out. The high beams still work. I do think its the fuses, since I switched the low beam fuse with the high beam and still had the problem.

    Do you have any idea what it could be?

    Are "relays" the same as fuses?

    Thanks
