$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

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.
