Headlight Plug Question
I have a 99 convertible, and it will not keep the headlight plug in. This is a round piece of plastic that covers the adjustment scren on the side of the headlight assembly. I went to a local dealer and bought a new plug, and it did not fit very tight. The first time I used my headlights, I saw it blow off.
Does anyone else have this problem? Is there a fix for this?

This is a common problem.
Yes, GM fixed this problem, but the new plugs are smaller than the old ones.
You need the new bezels AND the new plugs.
Try Gene .... not very expensive.

Parts Question
I see the parts on this page:
http://www.trademotion.com/partlocat...layCatalogid=0
My questions are:
1. is the driver's side called the left?
2. Which part is the plug that covers the adjustment screw?
I see the bezel is part #14.

Thanks! I will get with Gene this afternoon. I know it sounded like a dumb question, but for the sake of anyone who looks at this to know. Many thanks!

Just a couple small dab's of black RTV on the plug and seal the suckers in. If you ever need to remove the plug, the RTV will easily come off. It will hold the plug in but allow you to remove the plug when necessary. Thats how I fixed mine! Never flew off again!

The old style plug is actually a CAPLUG and you can get one FREE by going to their website and requesting one. As I remember it is either a 2 1/8" or 2 1/4" plug. the STEALERSHIP wanted to replace my covers for about $90. WHAT A DEAL!!!! I used black RTV on both sides and neither plug has popped since. The NEW STYLE has a retainer that SUPPOSEDLY keeps it there but I'm not to sure about that. DIY and save. I have one new and one old as the one headlight assembly was replaced. BIGHANK
BIGHANKCan anyone give a part number or style of the CAPLUG unit? I went to the site and its not readily apparent what we may need.

Capplug
If you still have the OLD STYLE its marked on the plug. The NEW STYLE with the notch isn't a caplug or at least it doesn't appear to be.
If someone has and old style not glued in with RTV maybe they can report the number here. Ill look at mine but think the marking is on the UNDERSIDE of the plug. I refused to replace my OLD STYLE housing when all I needed was a caplug. Tried calling all the local dealers but they had only the NEW STYLE.

Old and New Part Numbers
I just pulled the original cap plug from my right headlight. It has the part number:
9414
The new cap plug I just bought from a local dealer is part number:
9461
The new cap plug is smaller than the original, thus, it falls out.

Alliance Plastics also has one. The company I work for uses their caps and plugs so I had one of the buyers get me a dozen samples of their part numbe S2-1/8A. Basically a flat 2 1/8" plug. It's the same as the Caplug version and works perfect.

This is a easy and permenate fix.
Cut 2 circles from the tops of black spray cans. Super glue them in and they will never come out again. If you need to adjust the lights, just take the suround of with the 3 screws. I did this with my '99 and they work great.

I would not want to make a change like that to my car! I am a purist. I want it to look like showroom new forever. I will buy new bezels and plugs from Gene. But, thanks for your tip; someone will find it useful!
