Condensation in headlamp

5015 Views 15 Replies 10 Participants Last post by  Flesh
A few weeks ago I noticed some condensation in my drivers side headlamp but it was only there in the mornings but here lately its there for most of the day. Just wondering if anyone else has this problem. I plan on taking it to the dealer sometime here soon. Could it just be a seal or would the whole assembly need to be replaced? I hope it is a rather quick fix. Atleast same day kinda thing.

Might be a seal my sister's Mazda RX-8 rear tail lense did that.
if it is just a seal how long ya think it would take?

Not sure but you should just take it to the dealer and have them fix it.
Plan on it this weekend

Yeah it would be for the best just to have them do that.
did you ever get an outcome, cause.................drumroll please..................my driver side headlamp does the same thing. just wondering wht to expect for it goes to the dealer. <-----that is just the beginning of the problems though.........my newest problem, both CV axels are clicking uncontrolably during reverse and average takeoff, and left turns. :mad: :mad: :mad: :mad: the car has 11000 miles on it :mad: :mad:
Just drill a small hole somewhere in the headlamp housing that will let the housing breath, but wont let any water/dirt/moisture in. The corner lenses on my GTP were doing the same thing, so I just drilled a real small hole, probably around 3/16th", in the back of the lens where nothing could get in but the air could escape. Solved my problem and you cant even notice the hole. Its alot easier than resealing it yourself or dealing with the stealership.

If youre a woman though and for some reason dread the thought of drilling into your headlamp, I guess you could take it to the dealer. I'm sure there is or will be a bulletin on this.
Before I bought my GTP, I had read on forums that was a common problem. Sure enough, I started to get condensation in both my headlamps after only a year. I was hoping that the Cobalts wouldn't be the same... :mad:
condensation shouldnt be a problem with the headlights because the heat from the lights will evaporate the water, but i agree with gtp if this happens a lot drill a small like 1/8" hole in the top back of your lamp housing

Dont drill take it to the dealer its under warranty...
Yeah i got an appointment for tomorrow. Its just the driver side one. The water drops never go away, they are there all the time now.
my drivers side head lamp also gets condensation in it in the morning:(
Update...Just got back from dealer. At first the woman who you go to first said it was common and it just evaporates and the headlight is completely fine. Well I shut her up by saying if its COMPLETELY fine then its sealed right? Well where does the evaporation go when it does evaporate? LoL she just shrugged and called the technician over. Anyways he looked it over and after about 5-10 mins he came back and said A new assembly was ordered and it'll be in a few days
this is what i was told, the new cobalts do not have a sealed headlamp assembly, your front lens and the rear area are 2 seperate parts. therefor no seal from the factory.

done like this so if people crack the front lens of the headlight they do not need to spend tons of money getting a whole new assembly. because of this i can not think of a good way to stop the condensation on the headlamp but if anyone can prove me wrong on this one let me know because that would just mean that the dealer lied to my friend when she took it in. someone with some mechnical ablity want to take it apart and check it out.

if it is not sealed you guys might want to start looking for a different way to prevent the condensation.

P.S. - i do not own a cobalt but i work with someone who does and that is how i got this information. she is not on the forum yet so i am kinda posting for her. so dont bite my head off because i dont own a cobalt, if i could have paid 16,000 for one i would have one, but the RL was a better deal

I've seen brand new vehicles come off the transport like that at my work. Its been an on going problem for GM.
