    I noticed that when my car was new, (30 Jan 2020), when I had warm battery and went to charge, the cooling fans came on and the front louvers opened.....lately, when I charge, the cooling fans do not come on and the louvers do not open....I guess that is good in a way, but is it normal....I had made a service call to check that with a couple of other things and got a call this morning from Brad and he told me that unless I get a notice inside the car not to worry and tat the BMS issue doing the check and with no message everything is ok....he slap said that a software change may have changed the software programming and that could be the answer......does that sound possible or correct?

    When you first plug into any charger the louvers do a open and close cycle so you can test them that way. check out my thread about replacing my louvers when they weren't working. Spoiler: the 2 side ones are easy and the middle one is a bitch to replace
    Although when its not hot outside the fans don't ramp up much and when they do sometimes its only the middle louver that opens and you cant see that one you have to put your hand in front of it to feel if air is being pulled through.

    Does the car throw an error if these aren’t working?

    No there was no error codes talking about the louvers it was only that the battery was hot and that supercharging and A/C was reduced.
    If you look at the pics in the thread they were high due to the louvers not opening so it couldn't cool properly.
