Installed V6 tails, had moisture, carefully sealed up outside seams with silicone, work for a year or so, back again馃槨

Anything new tried lately?????

The V8 lights never had this problem, just do not like the look

thx

I used to have that kind of issue on headlights on a previous car. I drilled the smallest holes possible near the base at the front and never had an issue afterwards. Maybe that could be achieved on taillights as well.

Thanks for the possible solution.
The area that fogs up is the clear b/u light lower portion
It has a void in the construction of the lens, bad design IMHO
Drilling a hole would be a tough decision without someone actually doing it on the exact lens......

If you have taken the rear tail light assembly out you will notice the taillight has a space to allow for heat or condensation to dissipate. I would check the foam seal at the back of the light to make sure it seals properly against the inside body panel.

That seal is only for the large open upper panel area for stop & tail?
The part having issues with is the lower clear panel, it has a enclosed housing that seems to not be able to breathe.......

thx

Is the G8GT rear tail design the same as G8 except for lens color??

Did this on the tailights for my old Chevy Blazer, and it worked. For my G8, I just leave the battery panel off in the trunk. Seems to allow it to breath better.

Did your G8 fog up the lower part of the lens or everything??

Everything fogged up, but while the top part would go away, the lower lense would retain moisture. Now it's all good.

Took the first step:rolleyes:, ordered 1/32nd drills for my Dremel......

Very frustrating problem, one of those small details that stands out:confused:

Did you try removing the lights and letting them sit in the sun to dry out? Then reinstall them with the battery cover off. I would do that first before drilling.

Taillight saved me from taking action(y)
(for now)
It just cleared up, no sun, has been raining, I did not do a thing.
:unsure:
Must be a combo of conditions..................

I've been fighting this for years. Finally got pissed off enough about it I was going to take out the tail AGAIN and dry it out with a hairdryer but this time I was going to drill a bunch of holes in the bottom to let it air out better (the factory air exchanger is TINY) and hope it lets moisture out without new water in. However this time when I removed it it was below freezing out. The seal between car body and tailight had ice around the bottom of the seal. On one side the ice went halfway up the seal and stopped in a straight line. I've had this thing off quite a few times and never saw or felt a crack in the seal, but when I moved the seal around where the ice stopped there was a slash in it right there.

Dried it out with hairdryer, gooped up crack in seal with silicone, and installed back on car this time making sure the 3 10mm nuts holding it on were nice and tight to keep that seal tight against the body. I didnt realize how much water runs off the trunk edges and pours down the back of the tailight and how important that seal is.

You know i was thinking I should do that as mine were finger tight but it was raining when I put it back in (karma?) and didnt get back to it. Now that you said this I've gotta remember to add them tonight.
