Not sure if this is the right area for this, but it sounded good. Many times lately I will come out to my car at the end of the work day around 9 p.m. and get in to find the interior surface of the windshield is completely covered in serious condensation. Not a little like hit the defrost for a minute or two, but break out the towel and start wiping so I don't have to sit there for 10 minutes waiting for the defrost to do something and running the engine for nothing.
I haven't been using the sunshade lately because it's been overcast a lot so that's not trapping any moisture in there so I don't know what's causing it. I don't run the climate control constantly when it is colder, but go on and off as needed to maximize the battery availability. Is the car just sealed too well that it is not venting at all while it sits?I've never had it happen this bad before.
