    1999 Jimmy with Envoy package. Driver side low beam is burned out. Replacement from GM is $1200.00. Can I use an after market system? If so, how do I locate and remove existing HID ballast?


    1999 GMC Envoy w/ same problem - we removed the bumper then had easy access to the ballast (two bolts on top and one on the bottom if I remember correctly). For the bumper, there are two bolts visible on top, then two a bit lower just inside. Remove the 4 bolts then you pull the bumper forward to unlatch and remove it. When you put the bumper back on, insert the lower bolts first - otherwise it\'s a pain to get them back in correctly. For a temp fix we removed the ignigtor/bulb and ballast, took the wires going into the ballast (regular bulb wires) and connected a 9006 bulb. We removed the retainer from the ignigtor to hold the new bulb into place, it took some adjusting to get it set in place but it worked nicely. We will be putting new/aftermarket headlight assemblies in soon, but this fix only cost $25; it was a quick solution that took about 2 hours.

    One headlight shuts off then works again when I flip switch


    It's the Ballast. You have to pull the front bumper off to get at it. It's about $100 for the part. Good luck

    Trying to replace a front headlight bulb on 2001 acura 3.2 TL


    Look for the end of the wire retainer clip. Unhook it and lift it up. Remember not to touch the bulb. But if you do, just clean it with a bit of alcohol.

    btw - Here's a bit of info from a previous post of mine...
    The low beams consist of three parts. The bulb, inverter/ballast and the ignitor. The bulbs usually start to loose their color long before they burn out. The inverters/ballasts either go out after a while or take a while to start up.

    Before you spend money on a new bulb, try swapping it with the one on the other side. You'll need a security torx screwdriver to get the covers off of the back of the lights. Don't touch the glass bulbs. If you do, just clean them with a bit of alcohol.

    If the problem stays on that side, try swapping the ignitors. They're mounted inside the black covers.

    If the problem is still on that side you've got a bad inverter. They're mounted on the bottom of the headlight assembly. You'll need to remove the front bumper and remove the headlight assembly to get to it. (I recommend you take pictures as you remove things so can put them back together correctly.)
