Louver operation?

[kas81]

How is the louver in front of the radiator suppose to work? It seems like on my model 3 it's open all the time. When I took the picture in the morning the temperature was 16 degrees Celsius (60.8 Fahrenheit) and the car had been parked outside all night. Still the flaps/louver was open. My car was delivered in May this year and probably an April build.

Why is it you expect those to close? This isn't an ICE vehicle that needs to block airflow in extreme cold weather to warm up. And even if it did, 60.8 Fahrenheit definitely would not require reduced airflow.

i was totally hoping this thread would be about the AC vent louvers and why the hell they are designed that way...

not a fan

I just checked my car - louvers are closed it's 17 Deg C here

Looks like a visit to service centre for you

Holy crap balls- I never new this was a thing.

My car is in the garage and it’s 80 degrees. Louvers are closed. Every time I’ve ever looked in the past, they’ve been open.

They're fixed and don't move.

The are open when your eyes are open.
Who knows what happens when you close your eyes.

Definitely not fixed.

Here's a pic of my cars louvers - closed

I correct I had no idea. I wonder if a maintenance message appears in the service menu if the louvers fail?

When I was looking at various Model 3s earlier this year I noticed that some cars front louvers were open and some were closed. The difference? I’m not 100% positive, but the newer cars with heat pumps had the louvers closed when stationary, and the older cars without heat pumps were closed.

Thanks for checking!

I suspect mine is faulty then, despite no error message or warnings on the screen. My car is a M2021 with heatpump also at 2021.24.5.

No problem, glad to help out
Certainly looks like it's faulty unless something has changed with the newer M3's with heat pump
My 2019 has no heatpump

My louvers were open this morning 80 degrees. They were closed last night at 80 degrees.

No heat pump.

I suspect it’s for the battery, not the cabin.

Oops i just realized I messed up.

Heat pump equipped cars louvers were open, and non heat pump cars were closed.

71 in my garage. No heat pump. Louvers are closed (didn't know they were there until last night in this thread). Car has been parked for over 12 hours.

This made me curious. So today I found two model 3's parked almost side by side. One with heat pump and one without. With heat pump the louver was open and the one without the louver was closed. The temperature was 13 degrees C (55.4F). I don’t know how long the cars had been parked though, but this seems to match up on your discovery.

I’m a little puzzled about why the louver isn’t closing on the heat pump cars, even when stationary. Maybe it closes at some conditions when driving? Mine has definitely been open since I can see some bugs in the radiator already

I found this. It doesn’t really answer any questions, but shows that it’s definitely for the car cooling system. I suspect Heat Pump models will have different airflow needs than the old school ones.
