Like everyone else, I'm always looking for more efficiency where possible. Also like everyone else, I'm asking myself the question "Is this normal for this car?" about things. On this episode of "Is this normal?" The subject matter is the AC compressor. Here are the facts: This is a 2016 MX 7...

Hi, can you set climate boundary's? For example AC on when inside temperature is >76, Heat on when temperature is <70? Thank you Bob

When A/C is on higher speed 7+. Intermittently experiencing a strong vibration in steering wheel and foot pedals. You can not hear the vibration only feel it. The vibration is when car is stationary and can occur while driving. Adjusting the speed of HVAC will usually stop the vibration. It is...

My 2016 X just got update yesterday, 2023.12.5 and There are some new features in the service mode. One of these is a thermal test and it might explain some of what I have recently been experiencing, high power usage (460+) on the highway even when not towing. I will try to add the screenshots...

Is there a way to turn off the front passenger fan on the 2023 Model 3? I'd like to keep the driver side on. So far, I've been directing the air from the front passenger side towards the driver side as a workaround, but it'd be preferable to just turn it off separately. I was digging through...

Hi, About 6 weeks ago we purchased from Tesla a used 2019 Model 3 SR+ with about 28k miles. I noticed the A/C did not cool as effectively as my Infiniti but was sufficient. As the weeks (Southern California) got gradually hotter it appeared to become less efficient, I went into service mode...

Is it better to use auto climate control or should I adjust it manually to get a better range? I noticed that if I set same cabin temperature what is outside even then car will sometimes turn on AC.

Since April 2023 my Tesla is under repair for “P1-replace AC Components and HVAC flush” — why it takes more than a month - is mysterious. Model Y from Oct 2022 driven 6000 km. Tesla knows which cars has the potential problem - but don’t tell the customers…the error could happen anytime and...

I noticed my tesla model s 2016.5 75D doesn't seem to blow heat from the vents when recirculation is off. At HI setting, it still cold AC air. When I turn on recirculation and the heat then comes on. I had tesla replace the the actuator in this past December that was causing the vent to be at...

Several climate control issues have popped up over the last year (climate unavailable and vcfront447?) but recently with summer approaching and a Florida trip next month I decided to get the heat pump serviced… The car has 141,000 miles on it and it is very much out of warranty. They...

I am about to raise a service request mainly due to cold right (leg closest to drivers door). Any one else had similar experiences. I know I will be given the 'its nominal' sir. Which I will deal with at the time! It has cropped up several times on this forum with both the Y and 3 with heat...

So reading through information about climate control I came across a group of people who seemed to insinuate that using remote climate control to cool the car down, say while shopping and a few minutes before leaving the store, was extremely bad for battery longevity. But of course now I cannot...

Had a humming buzz sound appear recently. Located it to be coming from behind the little panel above the wireless charging dock under the front display. 23k miles is there anything I can do to make this go away or do I just need to replace the part ? Would Tesla do it under warranty ? Fan makes...

Noted the past few months that the climate control set to auto temp does not adjust or turn on right away when "starting" or driving away with car. This has been most noticeable recently with cold weather...get in set a destination, drive away and final heat and seat warmers startup about a...

Recently my wife and I have experienced about the AC or/and heat on driver’s seat would get turn on automatically when we get in the car and sit on the driver’s seat, even though the HVAC is off. We really can’t figure it out why it happens randomly. The auto cabin temperature protection is...

Hi Everyone. Looking for feedback if possible. My car is set to Auto Climate at med speed and at 21 degrees Celsius which I has been for around two years of ownership. Last month the AC started giving me issue. After 3 minutes the Auto Fogging comes up and directs flow to screen. I cannot...

I had a slow refrigerant leak on my 2020 MY that was causing dyed oil (yellow) to pool on top of my supermanifold and drip down the side. I scheduled an appointment with Tesla and they replaced it. If you happen to pop your cowl off for whatever reason, it's easy to see if you are having the...

I'm a new owner of a 2019 Model 3 and I encountered a strange A/C behavior yesterday. My wife was driving and I was in the passenger seat. She parked the car and went into a business meeting while I worked on my laptop in the passenger seat. Outside temperature was 9C (48F) while cabin...

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...

I have a 2018 Model 3 Performace I recently updated from a 2022.28 version to a 2022.44 version (I don't have wifi where I park). Shortly after (immediately?) running the update my heater stopped working. The fan blows but it blows cold. I was part of the group of people that had issues with...

Got a 2016 Model X 90D. I had my compressor replaced in August of 2022. It looks like TESLA service center did replace compressor, dryer and desiccant at the time...also did a "flush" as recommended in their maintenance. The bill was 1800+. It's January 2023 now and my AC went down again. They...

https://teslamotorsclub.com/tmc/posts/6715989/ See my post about the previous failures in the link above. It’s 39deg/f out and my 2020 MYP has a climate system requires service message and won’t heat… urgh! Now at 87k miles. Service has been notified and waiting to schedule. I’m so glad I...

Hi, Our just over month old 2023 Tesla Model Y suddenly started throwing below error. "Cabin Climate control system requires service/Climate Keeper unavailable due to system fault" I saw similar messages on forum but wanted to find out if there is any other solution except taking to SC...

A lot of Norwegians receiving their Model Ys (Giga Berlin production) have for some time now gotten failures on their heat pumps. The issue is supposedly due to a production error in the Berlin plant and metal particles that should not have been present are being taken into the HP system when...

Wanted to see if anyone else has run into this and how they approached it. My Tesla Model 3 2018 Heater has failed twice. Once 9 months ago, it was a slow fade out, each day a little less heat. Sometimes no heat, then a few days of heat, then all gone. Finally took to the SC and they...

Any idea ow to fix the cabin sensor reading higher temperature than the actual temperature? I cannot get my car blow hot air on AUTO setting since it thinks it is already hot inside even though it is cold. Service center said that it is normal. I have to take my car off from AUTO and turn off...

So I got to experience my 2022 MXP in cold weather for couple months now... It is obvious to me that whoever came up with the climate control and windshield algos lives in a warm, dry place and thinks the rest of the planet is just like that. The climate control in cold/ damp weather is a...

Hello, I just took delivery of my 2023 Model Y Long-Range a few days ago, and this being my first Tesla, I have a question regarding the Auto climate control setting. When I initially configured all the vehicle settings, I left the climate control in Auto and I noticed that this enabled the...

So it’s double digits below freezing in Ontario and I’ve come across an odd problem. When I have heat on at 24 on Manual mode and BOTH front facing and floor vents on, the air gets warm as expected. However, after running this way for a while, if I switch off the floor vents and only leave the...

When I purchased my M3 two years ago, the climate controls were the bee's knees. Being able to start both heating and cooling from the phone and having the interior temperature heat or cool so quickly meant never getting into an oven or icebox again. Fast-forward two years and it's all hogwash...

Hi together Since a few days I'm getting the VDS Message: #1452: HVAC: Low pressure according to the List it is marked as orange...(but I do not know what that means) So is it critical?...or just remark it while the next service? or can I even take care of it my own? many thanks for your...

I may be going crazy, but I seem to remember a time when if I was the only one in the car, the A/C would only display a temp setting on one side and the vent would only be active on one side. Every time I turn on the A/C (manual or auto), it turns on both vents. Its not set to "split" and...

Hello, I have 2017 Model X. About a week ago I smelled burning electronics inside the cabin and almost immediately after that heard a fuse pop. Then it was only cool air coming out of the vents. I knew it was the heater. I took the PTC heater off and took it apart. There are 6 IGBT-modules...

My 2017 Model S side windows are fogging up pretty bad and no climate setting seems to help with it. I notice that my front and leg vents have very low, close to no air flow unless I turn on recirculation at the highest fan setting. This isn't normal? I'm the second owner, so I had the cabin...

Hey y’all! For a while now, my 2021 TM3 (heat pump) has been experiencing heating issues by throwing error codes every so often, disabling cabin heater. Out of warranty replacement from tesla is charging $2,000 USD. A workaround I discovered to reset the system is to disconnect 12v and negative...

Hi there. It seems that my 2019 model 3 LR's PTC heater just gave up and died. My local Tesla SC will change the heater for 1000€, so I had a look and I can find used PTC heater modules for around 100€. Has anyone changed the PTC heater for model 3 by yourself? Any DIY instructions to share...

Hi fellow Tesla owners in the region. I have had my Tesla M3P since June this year and to be honest the AC is not working as I was expecting and definitely not as well as my previous ICE car. I set the temperature for 23 degrees and the air comes from below a bit but not from the centre. I try...

So its been getting cold and reaching 40 degrees when I'm leaving home in the morning. I preheat/condition the car and set it to 78-80 degrees in the morning. When I get in the car it feels nice and toasty but when I start driving with the same heat setting it doesn't blow hot air. Is there...

We've had our MY for just over 2 months and have gone on several road trips already. Love the vehicle, but haven't been able to figure out the climate control. It seems like the rear passenger was rarely comfortable, often super cold. Many times, the vents were not blowing air, regardless if...

Is there a way to view the climate control screen without air/heat actually turning on? If I wanted to turn on the heated seats or steering wheel without turning on vents, without using a voice command or pinning those buttons to the home screen, is there a way to do that?

It's only happening under the glove box, it's not a super big problem but it actually bothers me. I brings it to Tesla service they said they took apart the cabin filter and inspected for debris on the blower motor and found nothing. However, it was fine when it was back from service, so I was...

Hi all, 2013 model s, How do i make my ac cooler? Feel like its not cold enough like that new car ac feeling. Can i do it myself? If so any videos? How much does tesla service cost to fix it? Thanks

I inadvertently had R134-A with PAG oil added to my 2014 Model S AC system and now the AC is working intermittently. I know now this is the wrong type of Freon and can be damaging to the compressor. The question I have is: what options do I have now? (1) Can the Freon be vacuumed out and...

Hello, The ac compressor on my ‘18 model s is pretty loud and we decided to take it in to have it checked and replaced. One, not crazy about the diagnosis fee but whatever. Second, they came back with the report that we need to replace the ac compressor (what I told them all along) and they also...

Here's a quick PSA from @lUtriaNt on how you might be able to fix the HVAC smell issue in the Model 3 and Y, as well as some context. Hope this helps! This is a clip from the Tesla Motors Club Podcast #15. The full episode is linked in this article...

When I’m using the AC in Manual mode, and then enable Auto mode, there is a change in sound - even when all functions remain the same. For example: manual mode, 72 deg, fan speed 5, AC on, front and rear vents on, and recirculate on. Then if I turn in Auto mode after cabin has reached set temp...

My cabin fan is making noise - you can hear it especially on low RPM when AC is off. Not sure if this is a some sort of debris got stuck there or HVAC fan is just unbalanced. You can hear it on video: Not sure what to do here, I've tried to use a shopvac, leaf blower etc but it doesn't seem...

Happened a few times now. I use phone key exclusively. Drive somewhere, park, then move to backseat (e.g. sit with my kid). Car/MCU is “shut off” (screen off). Then a short while in, the fans will start blowing. Also, the app does NOT reflect that it is on through display or visualization...

Need some help from my roadster friends! Have a 2011 roadster sport and bottom line the HVAC system is not cooling. So this is a big concern with the battery! I need to get this resolved ASAP as battery is sitting at 34-35 *C. The circ pump is working and running continuously. I went...

Let me start by saying that the people at the service center were very nice. That being said, the rest of my experience totally sucked. AC broke on 07/02. System would no longer blow hot and cold air. The next available appointment was on 07/14, almost two weeks out. Brought the car in for...
