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!!!!
  • tidestertidester Posts: 10,110
    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
  • I had the same problem. I found a mechanic that could covert my 1999 envoy to standard headlights but GM would not send the parts. He was going to charge me $2000.00 for the job. After extensive searching this is what I did. I bought an aftermarket HID plug and play kit for 1999 envoy. I tore off the plates on the original lights and installed two brand new headlights for $250.00... no need to covert... Hope this helps. My new lights are two years old now.
  • This just happened to me and I fixed it today for $20 and it was really easy.

    Same story, passenger low-beam died and I was quoted over $1300. Went to a local auto store and bought the 9006 low-beam and the socket for it. Total $20. I removed the headlight cluster and took out the old HID light and igniter. Following the wire back to the ballast, I cut it and threw it all away. I left the old ballast where it was because it was a pain to get at. Next I cut the wires going into the ballast on the opposite side from the one I just cut. This is just the good old regular juice to make the good old regular headlight you just bought work. Wire the two together and you are good to go.

    You will have to make sure the new light is secure in the cluster. I used a short piece of metal strapping and screwed it right into the same holes. I may do the driver's side just to get them both out of the way. Total cost $40, or maybe $75 if you want higher end bulbs.
  • a little more input would be appreciated like what kind of conversion kit and what plates you tore off Pics if avalable would be a plus or mabie a website thanks:)
  • I have a 2004 GMC Envoy XL and my headlights will go out, out of no where. I am sure there is a short somewhere, but how do I find out where? Also, my air conditioner works up front, but the rear vents do not work. Any hints?
  • I have a 2005 Envoy and I also have this problem. Early morning after startup for at least 30 minutes, my lights will flicker.

    Just wanted to say thanks a million for your post. I had searched and searched for solutions to the Envoy HID problem with no luck. When we bought our 2000 Envoy the passenger-side HID, igniter, and ballast had all been removed already. I used some metal strapping to hold a 9006 bulb in the HID hole, but it was not a good long-term solution.
    So I decided to try the two headlight assemblies you listed from Vehicle Interior Parts on Amazon. $35/ea + shipping = not bad. They got here quickly and were well packaged and brand new.
    The passenger side was a breeze since the 9006 connector had already been freed from the ballast. The driver's side was tougher. I tried like hell to remove the ballast, but without completely removing the front bumper cover, it seemed impossible. Then I just tried to get the 9006 connector free, which was also a [non-permissible content removed] because it was impossible to get my hand into the space where it was connected. I fussed with trying different angles for a good half hour. I finally sent a long flathead screwdriver into the cavity and it pried off really easily (note to self for next time). At this point, the original assembly was now dangling from the ballast. I cut the wire as close to the ballast as I could and was finally free to install the new light. The wires barely reached, but they did.
    This is an excellent solution for those of us who prefer regular, easy to find, cheap headlights over proprietary redonkulously expensive HIDs.
  • I have a 2005 GMC Envoy. Recently while driving at night, they both turn off. This has happened to me quite often in the past week. I have had to ride the rest of the way to my destination with my high-beams. However, my fog lights still work.

    I have replaced the fuses for both headlights and checked the battery, in case a cable was loose.

    It turned off on me when the car was on but in park. It has come back on for me once. This was after I hit the top of the fuse box cover to lock it back in place and the lights immediately turned on.

    Could anyone tell me what else to check for?

    I like your way-BUT can you provide me EXACTLY what you BOUGHT & WHERE
    on-line and what your mechanic had to do exactly. That would really help my mechanic who I think will take this job on if its not going to be a nightmare!!
    Would appreciate additional info from you-it would really help.
    Thanks you much, in advance
    Doug

    susan72 (REPLY #19) Can you please provide additional Info on WHAT YOU BOUGHT On-line and from WHOM on-line and what your mechanic had to do exactly!! That would be of great help if you can do this for me.
    Thank you (INADVANCE)

    I followed all these instructions except I chose to take the bumper cover and bumper off. The same plug that is in the ballast fits right into the new headlight so no rewiring!

    Thank you for the help! Now I'll go sell the good side and the ballast and ignitor for the other. As it turns out, just the bulb was burned out but in the long run, the conversion will be more cost effective.
