hvac issues

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...

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...

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...

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

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...

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...

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...

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...

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...

I’d say that climate control in my 2020 Y has never been great, but since recent updates they appear to be worse. My Y does an excellent job of pre-heating and mostly keeps the car warm at slow speeds. However, when I get on a highway or drive above, say 35-40, cool and sometimes cold air can be...

Hoping someone’s had this same heater issue as me with my Model S. I can’t figure out what’s wrong I have a 2017 Tesla Model S 75D and it’s producing no cabin or defrost heat. Thankfully the heated seats and steering wheel work great or I’d be freezing. But it’s a bit hard to drive with a...

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...

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...

Interior temp constantly fluctuating between 122F to 72F. 2021 June delivered Model Y is parked in a 68F garage. Service Center could not explain. AC also blows cold air for 5 min and then just warm air regardless of setting. Any ideas? Are the issues related?

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...

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...

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...

Took my first long road trip today in my new Model Y (July 2021 build) and everything was great except the air conditioning. It seemed inconsistent. Sometimes plenty cool, even too cold, and then 30 minutes later I find the car is hot and stuffy. When this happens there seems to be low air flow...

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...

Hi, Is it normal that the drivers air vent doesn’t blow into the driver face? I’ve not been able to move the vent to achieve this thanks

Okay, I spent a while scouring for some information and haven't found any threads on this. I have had a temperature regulation issue and I am trying to decide if I just need to live with it or keep pushing Tesla Service on this. It mainly seems to occur in the first 10-20 minutes of a drive. I...

Has anyone encountered this issue? All of this happens on auto mode, in single temp operation. All windows are tinted including the roof, and I have the mesh roof cover. When outside is 75-85F, setting AC to 70 makes me freezing in the car. However, if outside is 90F+ and car has been driven or...

Hi: I have been working on my Tesla a bit in the last couple months. I believe the Heater has not worked since I bought it used in August 2020. My blower fan was "chirping" for a while, then completely quit. I replaced blower fan from junkyard. Still didn't work. Found blown fuse in Blower Motor...

Took delivery of my Model 3 on Christmas eve. Minimal mileage since then. Drivers side camera is not working - Service appointment for 14th Jan, Car / phone recognition works erratically which is annoying. Card is needed to unlock the car when returning from shopping. Shouldn't it recognize my...

Anyone observe odd ambient temperature readings on 2020.48.12.1? Yesterday, 30F outside and cloudy, I noticed my 2019 Model 3D+ displaying an ambient temperature reading of 102F: imgur.com After some time parked with climate running, it climbed to 103F, then went down to 90F. A reboot and...

So I fixed my defroster flap and now I have a new issue. NO HEAT. I ordered the DCDC fuses in case those were bad and almost bought a used PTC. I hooked up scanmytesla and am observing some interesting behavior with the HEATER R sensor and PTC air heater. HEATER R shows 415 degrees F and PTC...

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...

Hello everyone, I do have issues with the air conditioning, when I set it to automatic and a set point of 24 deg C (75), I’ll be fine for 20 – 30 minutes or more. Then I get hot air and the temperature in the car goes to 25 in the app. It’s really not comfy. I have to open the windows...

I’ve been having problems with initiating A/C in my model Y over the last several weeks. It typically just blows the fan and despite reset, toggling A/C, etc it will intermittently come on and cool. The service center checked it out and performed thermal testing and of course it was working as...

Quick question for those who have a Model Y already. So I have a LR AWD Model Y that's running 20.5.10.8 but have a couple minor HVAC issues that I was curious if others who have the Y were having. The first issue is that when the car is in park the option to turn on the climate keeper system...

Got this message when trying to set dog mode today. Tried setting a mobile appointment but earliest they can get here is April 8. Tried rebooting the car. Anyone else seeing this problem? I’m on the newest update.

I have two intermittent problems: When I set the Climate on and to 75F from the app, when I get to the car, it's cold. But get this: The app says the interior temp is 75F. It's not. It's not the 30F that it is outside... but it's not the grandma warm that I want it to be When the above...

Alright, probably a stupid question, but is there a way to tell that the cabin heater is being used besides feeling warm air coming out of the vents? I know it is more energy efficient to use the seat heaters, but how do I know the heat from the HVAC system is off? Thanks.

Hi all, I'm normally a pretty patient guy and have typically glossed over the small issues on our X that everyone has (MCU Yellow border, body control module issues, paint and interior quality challenges, window and door alignment, FSD/EAP features, lack of AP for the first x months, etc.)...

For years we have been complaining that our A/C has been making way too much noise, especially the little thump that it makes when it cycles on and off, almost once a minute. So now the A/C has finally died. Tesla service wants $3400 to replace the compressor and a DC converter. I don't...

So long story short, our MX HVAC is inoperable. Went for a 2 hour drive here in LA, had it set to LO and the cabin never got colder than mid 80's. Outdoor Temp was Mid 80's. I suspect our lines are crossed. Unfortunately last week when I called the service center to have them check out the loud...

I know this has been discussed before, but my 2 month old Model S AC is getting louder. Yes, I know it is getting hotter...! I've attached a short version, and a longer one showing how the AC starts and kicks in. In that one, you can also hear the AC unit step up and down responding to the...
