How To Get Rid Of Condensation

Nate,
getting condensation means: There's a water leak somewhere in your headlamps. This leak let water inside the lens, forming a clouding inside the assembly and looks kinda foggy. Condensation appears either of a leak outside of your headlamps, or it can happen when you clean your headlamps by using with high pressure. Also the best seal can not resist such high pressure of water, you know? Just in case you did it ;)

How To Clean Off Condensation
You have 3 ways to get rid off this condensation...

1. Temporarily Solution
Open the headlamp plastic cover(s) and remove the bulb(s). Put your car in your garage and wait 24 hours. The condensation disappears itself after this period of time. Unless the problem of water leakage is resolved, though, this will happen again and again. You can see, this solution is temporarily and sometimes not the the best. But it can help when you know, there's absolute no leak.

Just a side note: Please check the small rubber drain tubes on the bottom of your headlamps. All lamps have it, except tail light lamps. It is rarely possible they got clogged. It can happen but very rare. That means, the condensation will never go out itself. Just a thought.

2. Clean Solution
To clear up the inside of the headlamps, it must be removed and place inside a warm, dry environment for a minimum of 24 hours (inside the house is fine). Take out the headlight and shake/pour any water out that you can. After that, put the headlight in a small room with a dehumidifier on full blast overnight. All condensation will be outta there by the morning. After that you would go ahead and apply the silicone sealant.

3. Repair Solution
Take a pail of water and pour any water on your headlamps. If you see water comes into the lamps, then you have a serious seal problem. This problem is very easy to fix. It's just the silicon from when the factory sealed them has some how opened. I'd suggest taking them out and using the Oven Method to clean the inside and reseal them with a waterproof sealant. This link contains the steps of a Lexus headlamp, but the steps are exactly the same. -Mike

Hi Mike D. I don't plan on taking the headlamp out do to the fact you have to take the bumper off and the bodyshop just put the car back together a few days ago. The condensation is bad today as w/the other day it dried up completely, weird. Will look at it on my day off thursday. Thanks Man.

On top? Yes? Where? I didn't notice this. Or maybe that pic is kinda upside-down? You know what? I'm so clueless. And if it's true and I believe you: It makes really no sense to put the drain tube on the top :D -Mike

Sorry, my bad. I looked again and there are three on each, two on the bottom and one on the top. when I asked the question I only looked at the one on the top next to the two adjusting screws.....

Easy, guys. I think that the photographs are from JDM one-piece coupe units for the Legend. MikeD states that the link refers to the procedure for a Lexus.

Now as to why there would be a "drain tube" on the upper portion of a headlight space, I believe it would not be a "drain" until condensation built up in it and it then drained into the engine compartment. It might be more appropriately termed a "vapor drain" that equilibrates the humidity in the headlight assembly with that in the atmosphere.

Those with more insight, please correct me!

Vapor Drain Yes, that's it. You got it. Exactly the term I have searched for. Here another pic of our Corner Lamps. They have a Vapor Drain too. Thanks for clarifying :bowdown: -Mike

Here some USDM pics...

And the best is: I never knew that EDM's don't have this Vapor Drain. Maybe the reason too, that I don't have EDM's
anymore. I have the better ones... USDM's :bowdown:
