Can you take a pic of some Slate Blue H3's and Superior Blues. I have said before I do have a slate pic but i have to get the rest of the pics taken before we develop, six more to go!

I can't take pics at the plant. Sence the shutdown, there's not that many here now. I don't believe we've built any Superior Blues yet.

Thanks for the info, when will you guys start production again after the break?

do you know what this is i found it in the driveway i am assuming it came from my h3 but not sure

That's a plug. Maybe a body or frame hole plug. You have an oval hole somewhere under your truck that is very lonely without that.

If you can remember about where it was on the ground in reference to where your truck was parked maybe you can crawl under and stick it back in there.

My guess is in the rear somewhere

thanks PARAGON I crawled under there dam that's a soild frame but unfortunately i couldnt find a hole like that worst case scenario do I really need this

I would hang onto it and take it with you to the dealership. Let them find where it goes and put it back. I would have to think it is a plug that keeps water out of the interior

Check your dash panel (bulkhead/firewall). There is a GM part number on the backside, so the dealer can do a cross check with a H3 parts manual, and see where these are used and narrow the search that way (maybe more than one on the vehicle).
They also use these types of plugs in the bottom of the rear floor pan.

I got under my H3 with a trouble light (I like the neon ones because they put out less heat) and couldn't find a plug like that, although a lot of spaces are covered by frame and "stuff." Geez that's a solid frame.
I agree with the others, it looks like a floor pan plug, but it could be a lower firewall plug under your blower AC on the passenger side. PFM

Jersey guy,
to me is looks like one that would come off the bottom/side of a door. Like a back door, or side door. Not sure...but it is worth a check.

1) Go to the back of the H3!
2) Open the door!
3) Look to the lower door frame - right next to the right (as your looking at the back of the truck) tail light.
3) Take the plug you found in the driveway.
4) Stick it in there.
5) Close door!
6) Laugh - because you solved the mystery!


Not sure if I am right...but I hope so!

I looked up the part number and it doesn't come up. The underbody plugs are put in from the top ( inside ) and I believe there are 3 of them and they are round. Unless this is a old part number and I'll look through the old parts lists.

THANK ALL OF YOU FOR HELPING LOOKS LIKE VTSTOMPER IS CLOSE I CHECKED THEY ARE BOTH IN DOES ANYONE KNOW WHERE ANY MORE COULD BE I LOOKED ALL OVER CANT FIND ANYMORE

Man - and I thought I solved it.

I would check all the other door frames, and the doors themselves. If it is in the driveway it probably is from something that you have used there. Ins and outs so to speak...

Could have been dropped/stuck during production and just fell out when you washed it...?

Look under the swing gate itself. Might be one there.

LOOKED UNDER THERE NOTHING THANKS FOR THE TIP I WILL KEEP LOOKING

this is starting to bother ME! LOL!


If you have checked all the doors, and the inner door frames, my next guess is firewall or in the engine bay. I would not think that would be the spot...but by the way things are going it might be.

Just came back from the dealer i showed them the part and where the two are at the rear swing gate they said they think it is an extra piece that fell out from the factory. they think there are only two of these on the truck hmmmm i think they really didnt know thanks for all the help guys if anything new comes up please let me know
