Default Condensation in the Composite headlamp

I have a problem with condensation in my headlamps. On closer inspection one of the clips that holds down the plastic lens to the remainder of the housing is missing. 2 of the 3 clips remain....its getting really unattractive a bit irritating.

Short of drilling weep hole into the lens, what is a possible solution to this problem?

Here is a pic


Note the fogginess of the driver side composite lens

Thanks folks

I had the same type of problem on my Chev Astro. The GM dealer replaced the light assembly on three different occasions (one then the other, then back to the other side). After that, they contacted GM to see what else could be done. I am the type of person that FREQUENTLY washes my car...and I make sure to get into all the nooks and crannies. The constant temperature change casues the condensation (even when properly secured).

GM wanted to drill a small hole on the bottom backside of the light assembly. I was not happy with that at all...as I felt a mod like this was something other than what the light was designed for. I was concerned about getting dust and possibly even more moisture in the light. GM told me that if it didnt work that they would replace both assemblies again.

Well that was 3 years ago...and I kept that van for about 300,000km before I sold it. The fog lasted for about three days after they drilled the holes and then it was gone...never to return.

The fear I had about dust and moisture never materialized.

If your Aurora is out of warranty, I would say go for the drill...if not, take it to the dealer first and see what they have to say. Let me know what you do.

Another possibility, off the top of my potetially slanted head, is move it inside, take it apart (it is winter, the heat'* on, humidty is low) dry it, and re-silicone it.

use some rubber bands or something simular to keep them nice and snug while the silicone is setting. You might want to check and possibly do the other one too while you are at it.

Jim, check the seals where the bulbs plug into the back. I've had those leak in the past.
