    Took delivery of my new model 3 yesterday.

    I did notice a potential issue after getting in after parking it in a lot for a few hours. The AC fan kicked to high and was vibrating the interior. Not exaggerating, I could feel my arm vibrating on the arm rest, and in the steering wheel, and there is a loud buzzing sound. This happens at fan speeds over 7 or 8 (of 10). I’m assuming this isn’t normal, right? Probably the blower fan has a bad bearing or the fan is out of balance.

    Does anyone know if the blower is accessible somewhat easily, or is it buried in the dash? If easily accessible, I’d like to give it a firm tap, or at least try to see if it’s vibrating badly to confirm the problem.

    My M3 does this too. It's August 19 build so not too far off from yours. So I assume it's normal.

    That’s interesting. I had a RWD long range a few months ago before this car and it definitely didn’t do what the new car is doing. I made a service appointment, so I’ll see what they say.

    Anyone know where the AC blower fan is? Hard to find tech manuals for this car...

    Mine doesn't do this even at the highest fan speed. A buzzing noise would drive me crazy. I'd make a service appointment.

    It is in the front of the car behind the front fender. You need to remove Frunk bucket to access it.

    Mobile service came out, and it’s definitely the blower fan according to him. Unfortunately mobile has no way to access it. They have to take the entire dash out to reach it. Brand new car with 80 miles. Very worried about scratches, unknown missing clips and bolts after the service, etc. ugh

    Did you ever get this sorted out?
