ac 2 temperature setpoints

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...

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...

Hi all, just ran into a problem I was hoping you all could help with! My wife was supercharging our 2014 model S and after a couple minutes the ac started blowing super hot air. 5 minutes after that the car displayed an error message saying it couldn’t supercharge. Moved to a different...

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

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...

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...

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 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...

I’m super frustrated. I picked up my model Y in March. My air conditioning broke soon after. After the nightmare of trying to get someone at Tesla on the phone and a super rude person on their chat, I finally called the roadside assistance number and got ahold of a real person. She was super...

I’ve been noticing every day when I get in my car, the temperature (set to HI in the winter) is still maintained, but the directional setting for air flow is changed to the lower (towards the feet) direction instead of the towards the face setting that I prefer. Also, the toggle for A/C is on...

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?

Under normal conditions, do you guys always have your fans blowing? At what temperature is it considered “heating”? I usually leave my fans on at the 1 speed just to have some fresh air. Temp is usually at 63.

Since I received my Model 3 about three weeks ago, I have almost never seen anything under 300 Wh/mile. Usual range for me was easily 350-450 Wh/mile. Since it was new I didn't think much of it but eventually realized I had pretty poor range. I noticed a few guys talking about not using their...

Let's assume it is 40F outside and cabin temp is set 70F, would it be more efficient to use recirc with AC-on or fresh air with AC-off. I realize recirc with AC off would be most efficient, but the windows get foggy so recirc basically requires AC, at least if using for any extended amount of...

Is there a way to have the "Auto" setting for each section of climate control like in version 8 instead of Auto all?

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...

so is there any way to turn of the heater? i can’t find one. if the temperature selected is just a little bit warmer than the cabin, i see the red tinted air graphic, which i assume means the heater is powered up. The ac can be switched off in manual mode, but i can find no such option to...

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...

OK, again, why do we not have a section or two of this board dedicated to issues across the entire model lines? Like "Software" or "Interior" or "Repairs", when I post to the Tesla, Inc. section of the board I feel like it should be related to hiring or stocks or PR. Anyway: Every car I have...

This might seem like odd question, but I can't find any literature to answer it. The climate control in the Model X (and S) is pretty much automatic unless you manually set the blower controls. When it's in automatic mode, does anyone know if the compressor and heater are constantly active to...

I confess that I did not thoroughly scour the forums for this answer, so kindly redirect me if warranted. I took delivery on 4/1/13 in Anchorage, AK (no joke), and while winter is trying to give way to spring, the arctic forces are ahead at the moment. At any rate, the temperature last week...
