I have learned two very important maintenance related items for Model Y owners (and pertains to other Teslas I'm sure)
- I had to have my windshield replaced last week and evidently when doing so, it causes an issue with the "auto" function on the AC to only blow out of the top vent (defrost mode). Evidently there are a couple of sensors for the windshield, not the cameras, that require a software update to recalibrate. A soft reboot doesn't do the trick. Set up a mobile service request under the "software" option and request them to repush a software update (even if its the same version you are on. This will correct the AC issue. I did not have to recalibrate the windshield cameras.
