My passenger side tail light started to fog up on both corners. Their must be a leak in it somewhere. I know I've read use silicone by taking the tail light apart but these are genuine 99 spec and I really don't want to do that. Any suggestions on how to go about this?

 

I've heard of drilling a small hole in the base of the light to allow the moist air out. But I doubt you want to do that in this case.

I don't see why you couldn't drill a small hole in the back side of the lenses where it can't be noticed.

 

take them out and let them dry out inside and then around the seam put some black silicone and it should be fine

 

Ya I don't want to.

Other than I don't want to do that it wouldn't work because the back side isn't the same area as the lens. That would be the light housing and not the lens where it is building up condensation.

Are you saying that seam that is the black housing that the lens connects to by screws. I just looked at the lights before posting this and thought maybe I can do that. I'll pick up some black silicone tomorrow.

 

yea but make sure there is definatley no water in there before you seal it.. i did it to fogs once and the water was in there for a long time after that.. use a hair dryer to get the water out

 

Use a hot air gun and go around the corners to make sure some of the glue is seated properly.

 

I'll keep them in my house for a day. Then do an hot air gun around the seam lightly to make sure the previous glue is seated properly. Then I will go around that seam with black silicone. Think that will do the trick?

 

Sorry, should have been more specific. What I meant was the area between the lens cover (which is what you're referring to) and the lens. There's a small area between the lenses and the lens cover where both attach to the housing itself where you could drill a small hole (or a couple) to let the moisture out. That's if you don't want to take them apart.
No, because you're going to have to get the moisture out of the area between the lenses and lens cover first, and that means exposing that area to outside air by taking them apart. Otherwise, all you'll be doing is sealing the moisture in there.

 

but the way that moisture got in was through some leak somewhere. If I keep it in a dry area for 24+ hours wouldn't that leak just let the moisture out?

 

I doubt it, not in 24 hours. The leak is probably small enough that there really isn't enough room for substantial airflow to allow the moisture out.

 

A short drive on a highway/thruway (55 mph+) might be enough to clear the condensation out. Then you could try hot air gunning it.

 

I'd take them off and let them dry out, try putting small pieces of electrical tape around the edges.

 

oh ya i guess i forgot to mention it. The condensation is not visible after I get done driving or when I get home and have it in the garage over night.

So I think I can get the condensation out then hot gun it for a short while. Then seal the seams with silicone.

Electrical tape? Don't think this will stop the condensation. The leak is probably very small and tape won't seal it good enough.
