I just got my S75D on Saturday. When I picked it up we had the A/C running while the Tesla employee was going through the features. Once we drove off, the A/C was blowing hot air for about 3 minutes and then started working fine. It had just been connected to the SC's HPWC. This morning, I had it charging in my garage, and for about 2 minutes first driving, it was blowing hot humid air and then actually turned on. At my work, in open air connected to chargepoint chargers it seems to work immediately. Is this normal behavior? I'm wondering if it has to do with the A/C being used to cool the battery, which I know it can do, instead of cabin air. Maybe it has to do with being charged in a closed environment? The SC and my garage?
