2018+ models, GM removed the gasket and reprogrammed the blend door actuators to close firmly. I'm guessing by maybe increasing the shut-off current limit monitored by the CANBus?? Regardless, the doors now shut completely and there is only a very minute amount of air that can squeeze past the blend door. So now, the issue is still present, however it has been greatly minimized to the point where it only makes two little quarter to golfball sized condensation spots, one near each end of the defrost vent. I believe that 2016 - 2017 model years need to have the windshield removed in order to get to the gasket for removal and then a reprogram/re calibration of the blend door actuator control signal. OR....you can buy a small foam pad and cut it to fit over the majority of the defrost vent (like mentioned in these discussions), and eliminate the issue. If I had a 2016-2017 with this issue, I would go the foam pad route! Just a helpful tip for anyone reading this that thinks they have this issue, keep in mind that this issue causes fogging on the "outside" of the windshield...not the "inside". If you're experiencing this on the inside... then you either don't have your defrost controls set correctly for the ambient conditions...or you need to clean the film and residue from the inside of your windshield Last edited by Ten4Lou; 01-27-2019 at 06:37 AM. |

A few people who had the foam removed have stated that the process didn't solve the problem.

Ooh, that’s disappointing. That just reinforces the choice to use a dash-pad, rather than allow the dealership to remove the windshield and potentially mess something up. So far, everyone I know, including myself, who has a 2018, does not have this issue.

Mine was built November 2017 and it does not have this issue. The others I know that have 2018s also do not have this issue. Their build dates are the same or later than mine. |

My 2018 with a 5/18 build date also has this issue, and I highly doubt there has yet to be a fix. In a humid climate my guess is every Gen6 Camaro will have this problem. Kinda sad and definitely not safe....

I live in Houston. My brother-in-law lives in New Orleans. Can’t get more humid than that. Neither of ours have this issue. Both of us have ZL1, however I don’t think that has any bearing on the issue.

Nope, my 2010 2SS had the issue...the amount of fogging was just not as severe.

That is odd that you say that. I had a 2011 and I never had the issue, and I never had the issue on any other car I ever had.
