hvac has no heater off button

All Models: Eco-Mode - Reduce consumption of the Air conditioner by about half. Heater Toggle - Turn off the heater for the air conditioner to draw fresh air instead. Recirculation timer - turn off recirculation after 15mins to avoid high condensation. After using the Polestar 2 for three...

Having a single temperature setting means that either the heat or AC is on all the time. Being able to set a range where one gets ventilation only without heat or AC would be helpful in temperate conditions, or when the AC is on but the temperature drops in the evening. In the latter case...

I want to see a Texas mode that uses more fan speed (higher air flow) and turns on both front vents, passenger vent. I have to frequently turn down the ac to 66 degrees to feel comfortable here in Texas. With this mode I wouldn’t have to set the temperature so low and save battery.

The temperature in town yesterday was a whopping 103 degrees. I had to go to a store and was there about an hour. When getting back to the car, the temperature on the dash said 114. I turned on the Aircon and was driving home. Set the TEMP inside to LOW. All the way home it was blowing cool...

My 2019 Model 3 SR+ seems to have an issue with blowing warm air to the rear vent when it should be cold. This issue happens when mild cooling is required, for example, outside 76°F and inside temp set to 72°F. The front vents will blow cold, but the rear will blow warm. If air recycle is on...

Why is there no button to turn off the heat like there is to turn off the AC? Use case: in the summer, I might set the AC to the high end of the temperature range that I feel comfortable at. But, in the evening, that may cause it to turn on the heat, even though I would rather have it not use...

2014 Model S P85D I’ve got a strange issue where the cabin temperature whether in auto or manual will suddenly switch from cooling to heating on any temp setting except low. Meaning if it’s 90° outside and I have the interior temp set at 67° all of a sudden my car will start heating full blast...

I have a MYP on software 2023.20.9 and have notice that on some drives, my ac will not blow below 64 degrees (using a temperature gun shooting directly at the vents) even after driving for 30+ minutes when temp is around 100 degrees outside and temperature set at lowest setting. I know this is...

I'm wondering if anyone else is having the same experience, just want to confirm if it's normal. When I have the front and rear set to Auto and set the temp to 68deg for example, the rear air comes out much warmer. I can remedy this by setting the rear temp manually to 60, and only then will...

I am a new Tesla owner. I believe our climate control was set to Auto when we picked up the new MY. Does the car try to maintain the set temperature when it is set to Auto but nobody is in it? For example, when it is in the garage at night, will it maintain the temperature when set to Auto? My...

Drove 109 miles in MYLR yesterday @ average 100deg normal WPM for this round trip is 240 yesterday 309. Energy screen showed 51.5% of battery used for drive of which 15% was consumed by climate, thats 29%! Drive time was approx 3 hrs Climate set to auto 73 deg rear/passenger vents on. I have...

Hello. I know there are a few questions and posts about I didn't find anything current. I purchased a 2023 Model 3 in February. I live in Arizona and right now, yes, it is very hot. Temperatures about 117 during the day. My Model 3 is kept in the garage and is only rarely outside in the sun for...

We live in Phoenix, so it is hot, our 2023 M3 standard range at 80% was getting about the range shown 223 miles during the winter. In the summer we are getting less than half of that, we now get less than 100 miles. The energy app shows that all the energy is lost under climate (only occurs...

Hi Everyone I have been having problems with the AC since few days now. It has been fixed for a sensor problem last year but not sure if it is the same problem coming again. Unfortunately, my MS2020 went out of warranty only few weeks ago 😪 The AC suddenly and after a recent system update...

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

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...

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...

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...

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...

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...

After a week of noticing the air conditioner, here in sunny SW Florida, seemed to be intermittently blowing warmer than it ought to have, we got a notice on the screen saying HVAC system needed dealer service, and stopped working all together., this on last Friday evening. Research here talked...

After 4 Months of sending my Model 3 (December 2021, china factory) back to the service center for blowing on my knees and being told that "nothing was wrong" and everything being correct in the dash, it turns out that I was just the first of people noticing that the Model 3 with the new Heat...

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 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...

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...

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...

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"...

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...

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...

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...

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...

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.

Model 3 has a button to turn off the AC but unlike most other cars, it has nothing to prevent the heater from activating. Here on the Central Coast of California, it is quite cool in the mornings and evenings and unless I manually set the temperature way down until I hear the fan and heat go...

is it possible to leave the temp setting on auto, but turn off the a/c? I can do this in our past Audi's and Volvo's.....have a long trip later today, was thinking I could save some energy by keeping the compressor off.

Is there an easy way to tell if the HVAC system is heating or cooling? You can tell from the app by the color of the airflow arrows (red vs. blue), but I cannot see any way to tell from the screen inside the car. This may seem like an obvious thing but at moderate temperatures, it is not...

Is there any way to tell if the heater (or air conditioner) is actually on and using power. Often, the ambient outside air temperature is sufficient to heat or cool the cabin with fan only without using additional battery to do so. It may be a silly question but how does one tell?

Afternoon is still warm enough to require AC. Next morning I keep forgetting and after about 10 minutes of driving I realize heater is on. It is around 62 degrees out which is lower than the 72 degree setting in the car. In that scenario I don't want heater! I want vent. Keep the car cool until...

I'd like to spell out a couple different uses of fan only and implementation details. I'll need help on most of it and will try to update this OP with a moderator's help when it is well flushed out. 1. The easy one is fan only while driving. This just requires that Auto and AC be greyed out in...
