I have been experiencing a weird intermittent issue with my 2021 M3P. It has lasted for about a month or so.
Basically what happens is that when the condition is present, the climate control system only blows air out of the windshield and side window vents. The graphics on the climate control gui claim otherwise but even in manual mode, setting the airflow only to the passenges faces and fan speed to 10, you can feel that no air is flowing via the passenger facing vents in the dash. Thankfully the fan speed and temperature settings work and no issues with getting enough heat.
And now it gets even more weirder. When the climate control vent issue is present, the passenger sideview mirrors are also unresponsive. It doesn’t respond to anything: adjusting the angle or folding, no reaction. It’s a freezing issue as the condition can happen even when I’m parked at my workplace in a warm garage.
The reason I noticed the mirror issue is because my mirror has also been acting up on the passenger side. Every time I start driving the mirror is usually angled way too down. Then I manually set it back higher and save it - next time it’s messed up again. Have disabled auto tilt and even easy entry to no avail, the mirror likes to mess itself up.
So when the climate issue is present and I cannot adjust the passenger side mirror it is usually stuck in a really bad angle and I have effectively no right side mirror, thankfully the cameras work.
The issue has so far resolved by letting the car sit. The next day it’s usually gone. Steering wheel boot or power off, wait 5 min, power back on do not resolve it. And then it randomly comes back.
I’ve already booked service for 20th of February. Service menu error codes are not present when the faul condition is active. But I have seen evap temp sensor codes almost daily. And once there was a code for vcright MIA so I’m thinking could it be vcright that controls the passenger mirror and the vents - potentially a wiring issue?
Anyways it’s good to have the service scheduled, hopefully they find what’s wrong. I’m also thinking that it could be related to 2022.44.x firmware because the issues started after installing it. I’ve since gotten the bug fix update 2022.44.30 but issue still present. Perhaps 2023 firmware might fix whatever this condition is.
Anyone anointed in the dark arts of Model 3 control electronics? Would be cool to know exactly what vcleft, vcfront and vcright are responsible for and if the issue could have anything to do with one of them having isues (looking at you vcright!)
