Yea, wouldn't it be funny if I went to an MB forum and started saying how Lexus seats dont catch on fire....

But I guess I am better than that, thank you for letting me realize that.

 

Oh man.....that's why you STAY AWAY from the first redesign model!!!! What's next?? 6 speed tranny?? I can't believe Lexus haven't fixed this issue since the second generation GS

Lexus better get their S*** together. At $52k this is not acceptable...............

Where is Elizabeth?

 

My neighbor has an 03 BMW 540i and has had condensation in headlight since it was new. BMW told him that it was 100% normal, goes away when weather warms up or a lot of night driving.

Now that Seattle and LA climates have switched, guess our condensation will be a thing of the past. I have GS 300 2001 and it has condensation in drivers side only-still under warranty so its going back to be replaced. Just have to wait until it starts raining in Seattle again, so I can show the dealer;-)

 

wow this is unbelievable... i can't believe this is happening on the new GS as well.... drying out is not acceptable, coz' that leaves marks... how can moisture even gets in, sigh... sux man.... i would just go back to lexus and get a straight answer myself

and to many others, please be constructive and stay on topic. this is about the headlights, and stay on it. i don't want to see any fingers pointing and any personal attack, period

 

Everytime I've seen this problem it might go away temporarily and return when it condenses. It probably won't do any harm functionally but the moisture is trapped inside and can't escape. It could have been there during production. Since it is defective the dealer will have to write a warranty claim and order the new light Pod(s). The sooner it is ordered the better as this is not the first one I've seen reported here on CL. The others were stock cars and not delivered yet. It is not intentional on the dealer's part so just let them fix it. I'm sure you have already spoken to them. Parts will be scarce at first so that is why I urge you to act quickly. Let us ( and the world) know what happens.

 

So...based on this logic, on a cold day when I get in my car (which is sealed btw once I close the door) start it and let the engine warm up, but don't turn on my heat, come back out 10-15 minutes later and get in and blast the heat, the inside of the car is now filled with condensation??

You're dismissed.

 

actually yes, they will be... You never had condensation on inside windows? If you AC is off, and heat is blasting directly on the windows, then yes you will get condensation... Then you have to turn on the AC to actually dry the moisture of out the air. In fact, if you have digital air, and press windshield mode (whatever it is actually called) your AC will turn on automatically.

 

I don't have any experience with replacing a HID headlamp. Can someone tell me: is this a "sealed unit"?

If it is sealed then at the factory it would be gas "charged" or vacuum "packed" and there would only be wire terminals with a connector coming out. There would be no way for air or water to get in or out. There should be no appreciable moisture content in that gas or in that vacuum. If this is the case then the only way for water to get in the lens is for there there to be a compromise of that gas charge of vacuum and for water to find its way in through this break in the seal. And the only fix would be to get a replacement unit.

If there is a way to unscrew a fitting and the bulb then comes out of a lens - like the typical modern halogen, then this is not what is usually called "sealed". The halogen style system does create a "seal" with the o-ring but what it does is seal liquid water from getting in and it also seals air from coming and going - but there is air in there. And there is always some moisture content in air. (It is not the same as saying your car door is closed so therefore it is sealed - since your A/C circulates air from outside) So (in a system like this) if you were to install/change a bulb on a very hot and humid day then the air that was "sealed" into the lens cavity would have a very high moisture content to it. If the temperature dropped below a certain point (the dew point) then yes this moisture would condense (condensation) and you would see it. Once the temp for that pocket of air increases then the water will again go back to the gaseous state and you wont see it. And this will cycle with the temperature. I wouldn't think that this would pose a problem.

I thought of something you could try. Assuming that it is not a truely sealed unit, you could remove the bulb and use a heat gun/hair drier to inject a lot of hot air into the cavity, drying it out. May take 4-5 minutes. You certainly should be able to dry out the liquid water that you see.. Quickly replace the bulb - with as much of the hot (dry) air inside as possible. Now the air inside the unit should have relatively low moisture content and lowering the temp shouldn't cause much or any condensation. Once you knew it was dry you could then try a garden hose to see if you can get moisture back in there. Hopefully not!!

Taking it to the dealer is the easiest thing obviously. But if you try this experiment you might be better informed about what is really going on and be less likely to have to deal with the trial and error at the dealer. I personally hate going back and forth at a service center where it is claimed to be fixed and you find out a few days later that nope you need to go back again. Knowledge is power.

I hope this is helpful.

 

get cho dismissed face self *** on.


That would only happen if youa had the heat on probably and you had people in the car and you came back out and the windows would be fogged up and you would have to turn on the defrost to clear it up.


Tryin to treat with you self righteous ***.
Dont step to me cause it will be brought

 

Can somebody please this newb hes really starting to bother me.

 

can somebody band you?

 

Respectfully, let me add some info here. You will have to forgive me, my scientific mind is a curse! I don't mean to be correcting anyone - I just have fun explaining this stuff - so I hope it is helpful.

Condensation happens when ever air with moisture in it hits a colder surface. The surface has to be colder than the "dew point". The best example is when you are sitting outside in the summer with a cold beer or iced-tea. The air is warm and full of moisture. The beer is cold. When the warm moist air hits the beer it cools the air and it can no longer hold the moisture so it drops it on the bottle and it drips down on the table.

The hotter you make air the more water it can hold in it. That is why a clothes dryer works - it dries the air so that it is "hungry" for water then the water trapped in the clothes is eager to go into the air and away from the clothes. So technically warm air will in time warm your windshield and stop the condensation. By the way, when you exhale you are putting more moisture in the air and this too gets on the windshield. This is also why you can see your breath in the cold - the moisture in the air you exhale condenses when it hits the cold air outside. But you run the A/C because it dries the air by precipitating the moisture out of it. Just like the cold beer - as the air rushes over the condenser coils it caused precipitation - that is why your car leaks water when running the AC. So now the AC has "dried" your air - and when it passes over the windshield it can absorb some of that moisture - and prevent more from condensing. The air is cold but dry. It can absorb moisture - but not as much as hot dry air.

If the AC is too cold - colder than the outside air - you get moisture spots on the outside of the window just around the vent area? This is because now your windshield is acting like the beer bottle to the outside air. So a complex climate system like Lexus provides does even better. Yes when you hit the front window defrost button it does activate the AC but it also controls the temp to your setting. So now you have air that has been dried by the AC but also mixed with warmer air to warm it up. So now you have warm dry air which is even better at getting rid of the condensation fast.

Note that the rear defrost does not use AC - it uses heat! It has the resistive wires in the windshield that dissipate heat when electric current is passed through them. After a few minutes the windshield warms up and this eliminates the "beer bottle" effect.

Understanding these principals may help us figure out what is going on with these lights. With all of that said it may soon be time for a beer!

 

DO NOT LISTEN TO ANYONE WHEN THEY SAY THAT CONDENSATION IS NORMAL.

I went through hell trying to get that taken care of at the dealership. One of my headlights had moisture in it so I took it to the dealership and of course they told me about drain tubes and whatever. I made them change it anyways. Then a little while later it came back and I had them change it again. It happened one more time and I got mad so I went to the dealership and they tried to refuse changing it. Even had a Lexus District manager look at it and they both were playing stupid acting like im an idiot for even bringing the car to them. So I went home and made a post with the title of the dealership and wrote how bad it was and stuff. In about an hour and a half I got a call from the dealership saying heyyy whats the problem we have ur light in already, why did u make that post? Could u tell everyone on that website that we gave u good service and it was just a misunderstanding. I told them I dont want just one headlight changed now I want both of them changed because one is going to look older than the other. They did it no problem and I have not had a moisture problem since. This happened about 2 years ago.

That shows u this isn't a normal thing lights aren't suppose to have water thats embarrassing. Raise hell =)

 

LMAFO at the "Moisture in headlights is normal" comment. I cannot believe you are being serious about this. Not even my neighbors' 2003 civic coupe has crystal clear headlights. Only reason my Sc300 has condensation is because the body shop I took my car to after my accident gave me a junkyard headlight that was leaky. Things like this may be acceptable to you, but we trust Lexus to bring us "perfection" they even said so in thier company slogan; but even at this point, I guess it is a neverending "passionate pursuit of perfection"

 

Well, try explaining this to Professor Tupac above, I guess all of us have some science to learn
