Got an 05 trailblazer ext and the headlights are way out of wack. The driver side seams ok but the passenger side needs to be raised...a lot. Took a quick look at it tonight and didn't see anything obvious. Is there a thread on this? or can somebody help me out?

Thanks

to adjust the headlights you have to open the hood first.. on both side's of the faring for the radiator right next to the bump stops for the hood the is an oval hole.. you will need a 1/4 in deep well (might be bigger have not adjusted mine in awhile and cant rember for sure) with an extension .. you will want to be on lvl ground in the dark to adjust them.. but you turn the adjustment screw to adjust up or down.. if the driver side is ok try to get the pass side the same hight.. then you will want to check the high beams while your at it.. same adjustmen screw but you might have to compromise between the two.. i can get a pic of it tommoro durring the daylight and follow up on the post for you.

I would like to add to this thread as I feel it's pertinent info. I was adjusting my headlights as well and upon raising them, I believe one of the mounts came off the threaded adjuster. I cannot lower the headlight but it doesn't wobble either.

For the OP who needs to raise theirs, keep this in mind.

Anyone who has had this hapen is there a fix to reattach the threaded portion?

Here is an old but reasonably accurate method that has served me well. Trouble is I have not tried on my 05TB with our newer headlights. Anyway. on a surface like your garage, keeping the vehicle straight, drive up close to flat surface like a wall. It can be anything that is in front of the lights. Turn your lights on high beam and there will a "spot" of light on your wall in front of each light. Mark the center of that with a piece of tape. Now backup about 10-15 feet. hopefully you lights are still centered on your tape. If not adjust and you're done.

Like I said I haven't tried this on our type of lights but this works really well on "old fashioned" types.

Enjoy.

Went looking for what you described. Found the assembly on the drivers side and understand how it works.
Unfortunately, the entire assembly is missing on the passenger side.
no white torx screw
no mating black nut
just a metal post with grooves on it.
Just Like gmcman said above...:mad:
Is there a reasonable replacement part out there? I don't want to buy another light for such a small portion of it.
In the mean time, I am trying to rig something up...
I fought with it for a while and got it to turn by hand. yanked up the light angle, and put on a zip tie to hold it. Very Temporary. Anybody got a better idea? BTW, I havent even tried to align it yet. Just trying to figure out how to attach it first.

Just fought with it for about two hours. Finally came up with a pretty slick solution. I went to the local hardware store and picked up some push on clamps/washers. The kind you push onto a bolt or rivet and tension holds it in place. I picked up six (all different sizes) for less than $2.00. After some trial and error I found the right one. I would recommend a couple of things:
1. Put a larger washer on first to make sure the push nut has something to push against.
2. Use needle nose plyers to lock the post in place when starting and pushing on the push nut.
2a. this was much easier after I "accidentally" broke off the mounting bracket of the torx screw with my plyers
3. Adjust the light to almost the proper height using the directions provided in this thread before pushing the push nut all the way on.
4. Finish it off by twisting the adjusting bolt to provide extra tension.

Here is a picture of the push nut I ended up using
