Headlamp Housing - Condensation

Back in a Bowtie · January 21, 2015

Maybe it was the environment they were built in that caused the issue. If at all possible, pull the headlights completely and let them air dry inside your house for 24 hours. I also hit them with a blow dryer so the hot air could help evaporate it. So far no issues but if that doesn't solve your issue then I would recommend taking it back to the dealer and let them know what you did and if they are cool they will just replace them no questions asked. The dealer I go to (but didn't buy my truck from them) asked me a few questions and then just said bring it in if it happens again and did we'll replace them. It was about a 30 sec. conversation lol

thanks for the info. Yea they seem to be clearing up more now, i have the truck running, highs on to try and burn it off. plus i have a long drive tonight so that should help vent it too. Well see what happens

So far I haven't seen any on my Silverado, completely stock setup.

I think the key message here is once condensation sets in, it may dry up from time to time but will always return (at least on the Sierra housing). In my case I was adamant that it's not right, my servicing dealer agreed with me and will change the housing for me. They had to order it so I'l return next week and have them swap it our for a new one.

Anyone experienced this problem; Headlamp housing condensation? If you have, did you're servicing GMC or Chevrolet Dealer replace it as a warranty item?

I woke up this morning to find my truck, '14 GMC K-1500 Sierra Denali in the garage with the left headlamp housing clouded up with condensation. No visible cracks, chips, scratches, etc., The right side lens remains clear....

Update 01/27

My servicing GMC dealer changed the headlamp lens housing as a warranty item.

It seems like more and more people are having this problem. I have a 14' Sierra All Terrain and am having the same problesm with moisture/fogging at the bottom where the LEDs are. Noticed right after i got my truck and called the dealereship up and they replaced them the following week. The new set they installed had noticable fogging the following day. I live in south Ga where humidity is a constant problem. Guess ill just have to deal with it until GM decides to do something about fixing this.

Yall could always buy aftermarkets and sell the stock ones to put some cash back in your pocket. I know you're still forking out more money, but in the end you won't have to deal with them fogging up

A took delivery of my truck a couple weeks ago. I noticed a very light fogging of the lower area of both lights.

I took the bulb access cover of the drivers side and went for an hour drive. When I got back home all the condensation was gone so I removed the passengers side cover as well. After about two hours, sitting in the driveway that light cleared up as well.

I think the issue is lack of proper ventilation. Removing the covers allowed the moisture to rapidly escape.

I replaced the covers and the condensation hasn't returned to this point.

I'm surprised guys are getting these replaced... there is a TSB from a few months backs telling the dealer to specifically NOT replaced the fogged headlights on the Sierra.

My servicing dealer replaced my headlamp housing that had developed condensation without hesitation as a warranty item.

Just got out of the car wash, it's about 45 outside temp right now, got home and my entire driver side head light was fogged up. Not just the drl strips but the entire thing. Haven't noticed it that bad before, I'm going to keep an eye on it.

Update: Brought truck in for 7500 mile service and mentioned the fogging in passenger high beam. i said "i think it'll go away when the weather gets warmer, just want you to note it now incase it doesn't go away." i said nothing about my HIDs though i assumed they could tell. While i was waiting for the rest of the service to get done the guy walks through and said hes going to order a headlight housing for me. Should be here monday and installed next week.

I don't know what to do about the HIDs... should i unistall them before they do the swap? leave them and they'll handle it (drill the hole)?? will they use the old cap with the hole pre drilled? what if that was the cause of the condensation?

They wouldn't do anything past replacing the headlight pod and adjusting the beam. Take the HID out, replace the caps with unaltered ones.

so you think my best move for now would be to remove HID from the one headlight and replace it with the factory bulb. Then once the new housing is in re-install the HID?
