    How's Your AC Holding Up? My Compressor's Loud, Failed 3 Times in 3 Years, and Struggles to Cool. Also "same" repair jumped from $1,195 → $2,030.

    Greetings all. Have a 2017 S 75D with ~185k on the clock. Very pleased with the car but running into systemic AC issues - specifically compressor (part number 1063369-00-J) failures - see my prior post on the subject for more info. What's currently happening: AC compressor is becoming louder...

    HVAC Auto mode keeps fan on high?

    HVAC Auto seems to keep my fan speed at 9 seemingly forever. My car is in a climate control garage at 23*C ambient, and turning on AC Auto has the fan blasting at 9 regardless if target temperature is 16C or 23C or anything in between. This morning's commute it stayed like that for the entire...

    Can I walk-in service center if my model Y AC stopped working in hottest summer days?

    Hi, My model Y AC stopped working when I’m driving long trip, I’m driving on highway with 104 degrees interior temperature today, and feel like dying. Also my heat point is activated the whole time, making loud noises the whole day time. The earliest appointment available is 17th, have anyone...

    HVAC Refill Procedure and replacement Condenser

    Working on getting #803 into shape. I have finally sourced a replacement HVAC condenser (if anyone needs one, will be posting pictures of the newly fabricated one). No SC nearby so need to take it to a regular HVAC shop. I haven't found a comprehensive guide here for the procedure to replace...

    Model S60 AC Intermittent and Making Noise

    Last summer during a really hot day (40+C), my AC just stopped working, which was quite scary because we had to get our 5 week old baby home asap before the car got too hot. According to the teslafi log, it got up to 36C inside. Later that day I hopped in my car and it worked just fine and we...

    HVAC Cooling Performance Degraded

    With spring arriving in the Midwest and the warmer temperatures, I've noticed that my 2018 Model 3 is experiencing issues keeping the cabin cool over a few drives in the last 3 weeks. During the past two summers I've kept the AC around 70-72F in the summer with no issues. This year I'm having...

    AC and seat heaters malfunction

    I am not sure exactly to what degree my problems are malfunctions or features so I have to describe it all. AC set on AUTO only turns the vents up (windshield) no matter the temp - LO all the way to HI. When I switch to manual control it seems that it works as intended. Then it gets annoying...

    Model Y Air Blowers on face

    Hi. I still can’t do it. Couple of months in. Has anyone managed to get air blowing directly onto their face (driver side)? If so, could you please show me your airflow graphic. It’s crap. Far worse than the model 3. Many thanks

    Climate Control Nightmare!

    Hi all My Climate Control has gone AWOL. Was blowing cold air no matter what the temp was set to, even on full blast heat! Went into the SC for 2 days, sensor change out apparently. Few days after that, we’re back to cold/tepid air at best. I’ve literally just set it to 26 degrees there and...

    Air flow to my face

    How do I get air to blow in my face. Quite a warm day in the UK today and wanted the cool air blowing on my face but after playing for the nearly 2 hour drive, I couldn’t get it any higher thank my waist / knees. Not normally and issue but just felt warm today and would have liked the air. Think...

    3 Days after Delivery: VCFRONT a447 Error

    Was reading previous threads about VCFRONT climate errors and most have occurred in cold climates. That's not the case here as temps have been in the 50's (F). Have had the car for a whole 3 days. Already submitted for a service appointment for an interior trim issue and just realized the app...

    MAJOR breakthrough in HVAC control (heating with single occupant)

    Okay, so I'm an eco nerd and hate the impact that driving in the winter has. I've had my Model 3 through 4 winters now and just today (with the help of the Scan My Tesla app) did I discover that you can go manual temperature control, split the HVAC for left/right controls, set the passenger side...

    Voice command to turn off a/c condenser

    Is there a dedicated voice command that will only turn off the a/c condenser, but leave the fan running? I typically do this in other cars a couple miles before reaching home so the vents dry out, to prevent the moldy smell. Right now I have to tap the temp, then push a/c.

    AC vent constant medium/high pitch whistling noise when climate is on, normal?

    Hello, Took delivery of brand new 2022 Model 3 RWD a few days ago. Noticed that when I have my climate on, my fan speed at 1, 2, or 3, and any temperature above 20 degrees Celsius, there seems to be a whistling/whining noise coming from the vents. This is regardless of whether or not my A/C is...

    Is there a way just to let some natural air in without the windows?

    Hi, I am in a black tesla, and it is really cold outside, but the interior still gets really hot because it is black. Is there a way to just let the outside air come in through the filter and into the cabin, that is, just to get some fresh air in through the outside without turning on the ac...

    HVAC Failure, Replacement, same issue again...Ideas?

    So we had a pretty decent snow fall here in Eugene, OR about 2 or 3 weeks ago. First day of 30 degree weather I noticed my 2019 Model 3 LR AWD wouldn't pre-heat from the app, it would turn on for about a minute and then turn off, and when I tried to turn the climate back on I received a "Climate...

    HVAC turning on while car is parked and no scheduled departure (preconditioning) set

    I just received my car so apologies if this is a stupid question. I also did a search and did find some matching posts but they kind of tapered off without any solution; so hoping to find a solution. A couple of days ago, I went to the app and set Scheduled departure at 6:30 am and turned...

    HVAC button with halo

    I swear the HVAC button in the app looks different every time I look at it! Sometimes there is like a halo around it and it seems to be glowing although it is actually off. What does that mean? I think I get it after driving in cold weather and the battery is still warm but the car is actually...

    Do you use A/C during winter driving?

    I'd be interested to share my experiences with winter driving of my Model 3 in terms of using / not using A/C. My thoughts are: - Whenever climate is set to Auto, the Model 3 (almost) always turns on A/C. It's not just the blue button, it's the smell of the A/C-treated air, it's surely running...

    Windshield replacement and Climate control

    Hi, I wanted to share feedback as i found this on a few places searching online and recently had the same issue. As i reported before i cracked my MYP windshield at around 2000 miles. This was replaced at a Tesla facility. A few days later i found the problem with climate control. 1. when on...

    Location based climate control?

    Sometimes the set temperature changes automatically when returning home and pulling into my driveway. I think it has happened on both auto and manual HVAC modes. I know that mirrors and suspension height can be location sensitive, but I didn’t think that climate control was. Also, while changing...

    Interior reported temperature incorrectly high after windshield replacement

    After front windshield replacement, two issues began to occur consistently 1. Interior temperature of the car is detected to be unreasonably high after overnight sleep. The interior temperature shows as high as 37C/99F immediate after car wake up, where the ambient temperature is 12C/54F. The...

    Air conditioner fails twice in two years - advice appreciated?

    Short version: I replaced the compressor in my 2014 Model S just two years ago. Service is telling me it has failed again and want to charge me $4000 for the full fix. Something feels off about all this, and so I'm seeking advice. Longer version: In 2019, I bought a used 2014 Model S85. I...

    HVAC Control - for those over 50

    30 years ago, most houses had a thermostat with two settings: How LOW the room temperature will go before the HEATER kicks on. How HIGH the room temperature will go before the A/C kicks on. Yes, you set a temperature range. There were two slider adjustments to limit "how warm" and "how cool"...

    Strange HVAC issue since windshield replacement

    Here's a new one for me. I had my MY windshield replaced this past Tuesday (OEM glass, 3rd party installer) and when I was driving to work on Wednesday morning the AC, which I always keep on "auto" at 68°, decided that it only wanted the air to come out of the windshield and foot vents. It...

    Pro Tip: Setting the climate 71F or lower uses less energy in hot weather

    With hot Summer weather approaching, I thought to point out that setting the climate above 71F consumes about double the amount of energy. Intuitively, the thinking is setting the climate warmer means the a/c runs less often. The reality is that in Teslas, it creates heat to get the air to the...

    HVAC not blowing evenly on driver's side - centre position

    For a while (maybe since I got the car - I don't recall), I have noticed that the air doesn't blow very strongly in the centre position on the driver's side. On a hot day I can still be sweating away while my passenger is freezing with the air running at full blast. I can feel with my hand that...

    HVAC replacement prior to solar+Powerwall installation - Daikin Fit?

    I'm replacing two HVAC systems now before installing a solar panel + 4 Powerwall system in the fall. I've narrowed the compressor choices to Daikin Fit variable speed (2 ton + 2.5 ton) that will go on the existing ducted systems. Am I correct in assuming that these should be able to start & run...

    Hi all, October Model Y build here with an AC and heat issue. If I put the car on LO or HI, both cool and heat works great. The minute I change it to 70, compressor starts cycling on off on off for about a minute and then fails. When this happens, heat and cool fail for the rest of the day, and...

    Clicking sound coming from climate system fan

    I actually started noticing this last year around this time but it mostly went away during the summer months because the fan speeds were usually much higher. It's a high pitch, high frequency, "clicking" sound coming from the climate system. It's not a very loud sound, but very noticeable at fan...

    HVAC barely blowing air (possibly blocked somewhere?)

    Within the past couple of days, the HVAC in my 2020 Model S has been behaving funny (and poorly). Regardless of the fan settings, there's no more than a trickle of air coming through the vents. The air is definitely conditioned (it's cold and dry) but the volume of air is very low so it...

    Air conditioner cutting out

    Im thinking this is a service call. Hoping a member can test to make sure its not how its supposed to function. This happens more apparently when the car is hot. so turning the thermostat all the way to low from a normal temperature will increase the fan and cooling. It will work fine for 3-5...
