Interior Moisture Problem

[No_ICE]

It's really raining here in Southern California. Went out in the rain in our 2021 MYLR for dinner at friends. Parked outside for about 4 hours. When we went to leave the inside of the windshield was soaked to the point of almost dripping. We turned on all the defrosters and had to wait about 5 minutes to get the inside of the windshield clear enough to drive. I have had fogging in other cars while I was in them but never had wet like this when I was not even inside. It was like there was some opening to the outside air while parked. Yes, had I known it was wet inside I could have turned the defroster on before I entered but I didn't know it was wet, and never expected it to be as wet as it was. is this common in wet weather for the MY?

Try calibrating the window actuators. See Tesla Model Y Owner's Manual, Page 13.

Check the security settings, check the box that closes all windows when locked.

In colder weather the Tesla Model Y will lower the window by 1/4". This can help prevent the window from freezing to the door seal (but not the seal at the bottom of the window where the window lowers into the door frame.)

My wife’s MYP acted like this when it was new until we scrubbed the presidue off the inside of the windows. Seemed like a strange suggestion from another feed, but the problem went instantly away.

I don't know if this is related, however, since the last update to my Y 2021.44.25.2, every window rolls back down, maybe a fraction of an inch.

That is a feature, not a software bug. It is intended to help prevent the window from sticking to the door seal in freezing temperatures when wet.

Ah, I just walked out to my partner's Model 3 windows, and her's just go up and do not drop back down at all, interesting the slight behaviors of the Y vs. 3.

Can I ask what you used to scrub the windows? I really need to do this on my M3, I’ve tried Fast Glass but it’s not really doing the job.

I use this Glass Cleaner | Sprayway Inc., Pioneers in Aerosols since 1947 based on suggestions here on the forums.

Here's some fun... if you read over on the Feet are frozen thread, you'll see my challenges with fog and no airflow unless on recirc.

Took out the filters in the frunk (charcoal + hepa), and they are SOAKING WET - which is the likely cause. Trying to dry them out inside tonight.

That sounds like a mildew/mold cesspool waiting to happen

Mold and mildew will only grow when the temperature is above 70F (21C) and the relative humidity is greater than 60%.

Really simple — bucket of hot soapy water and a micro-fiber cloth. We just rubbed it until it felt smooth to touch, then dried it with another microfiber. Simple.
