heater

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...

Wondering if anyone has used a Tesla PV/ESS setup with on-demand / tankless (specifically electric) water heaters? TL;DR...could you split a 36kW tankless electric water heater across both your backed up load center and non-backed up (main panel) to have some hot water in the event of a power...

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...

As an imminent MY customer, I've been paying attention to the various threads about Heat pump problems. At the moment these are mostly stories of inoperative cabin heating/defrosting in extreme winter conditions. However, there are also older threads floating around about weak or occasionally...

Hi there, I have the problem that the front window defrost switches itself off after a while (on trips, while driving). This is not the case with the rear window. I noticed this when the front window started to get foggy on a regular basis on our journeys in winter and the corresponding icon...

Model S, Extended Range, born on 5/2020. Delivered 6/2020. My Climate Control has stopped functioning properly. In addition, COLD air comes into the passenger footwell regardless of setting. If you turn off CC, there is a cold breeze blowing in around the feet of the passenger. This is after a...

Rumor is that the Model Y will get rid of the PTC heater in favor of a heat pump with a significantly redesigned cooling system. I have always wondered why Tesla didn't follow the other brands who offer a heat pump for us who love cold weather.

My spouse and I were on our way home from Cape Cod after watching my grandson play in a hockey tournament yesterday. it was quite cold, low 20s (F) and windy. On the trip down to the rink, the heater worked fine. The trip was more than 60 miles, plenty of distance for the cabin to heat up, or...

A main reason range is significantly reduced in cold weather is heating the passenger compartment and the battery. It would be nice if Tesla would show energy usage of this heating and how much it is effecting range. This can help people appreciate the issue and perhaps get them to reduce...

I own a 2018 M3 RWD and the following is some information I gathered using SMT. With the car not plugged and the ambient temp around 48F the car draws 3.5KW to heat the traction battery and about 7KW max to heat the cabin for a max total of 10-11KW. When the car is plugged into my [email protected] it...

I understand that using the seat heater instead of the cabin heating is more efficient, but if the cabin is cold I find that my hands get a bit colder than I'd like and also, the windscreen and windows start to mist up so I really need to have some cabin heating. So I'm finding that while...

I don’t know if it’s just me but the driver side foot vents on my car don’t warm my feet much at all. They DO blow air I can feel it rising past my steering wheel bottom. But the direction they point definitely doesn’t feel like the foot pedals where feet usually rest :( ..minor gripe of the...

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...

Bought my Model 3 last June and brought it to South Korea with me and now experiencing my first Winter here. Really frustrated how the heater does not work. I’ve watched YouTube videos explaining how it needs time to heat the battery before the heater blows warm air. I’ve driven it on long trips...

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.

I took my M3 into the SC after reviewing posts about people having the same problems i had (have). The heater, on auto, on hi doesn't blow that hot. and for whatever reason only blows in the floorboards. so, i turn it on manual and turn it to hi and 10 blowing just out of the vent. it blows...

I have a 2015 70D, and yesterday the heater started making weird noises. Initially, on my way home, it made sort of a repeated clicking noise - kind of like a fan hitting something. I turned the heater off the rest of the way, and hoped the windows wouldn't fog up. This morning I tried the...

Hi there, any Tesla model 3 owners who have installed a diesel cabin heater? I found this user story on insideev: As demonstrated by commenter Stanislav Jaracz in New Jersey, you can install a diesel/petrol combustion heater for less than optimal plug-in driving days. All the heat you want -...

Hi, just picked up a new MX last weekend (great service from Heathrow new customer collection team, btw). Having gone over the entire car very carefully I've found a few minor issues which I'm sure can be fixed in the bodyshop and will get it booked in (mostly alignment of chrome and a couple of...

Could this sudden drop be due to my using my heater today? Thanks very much.

Hi folks, A quick few notes. I normally get around 135 Wh/km on highways in weather where I need no AC, heat, or open windows. Maybe windows are cracked a tiny bit, or low speed fan-only. LR AWD is rated for 150 Wh/km from what I can gather. Temperatures in degrees C. Range in km. Because...

We will be doing our first long road trip with our Model 3 LR AWD starting on Sunday. It may be fairly cool on the morning we leave (temperature around freezing is forecast overnight), so I'm seeking advice on how to keep a warm enough temperature in the car while minimizing impact on range...

so.. a friend has a weird problem with ptc heater.. maybe you guys can help out. Blows only cold air even at HI heat, then maybe after 30seconds blows really hot for a few seconds, then again cold air for next 30sec, then hot for a few seconds.. cycles like this. AC on/off has no effect.. model...

2014 model S. The wrong heater/AC vents are blowing. Sometimes the Heater/AC will blow on my feet or the windshield even though I have selected the mid vents. Switching to the floor vent will some times get the mid vents to work but very little at the floor. Changing fan speed or recirculation...

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...

Winter questions - 1. I remember with my Model S, the heater kinda sucked. My feet were never warm. How is it with Model 3 with an outside temp. of around 10F? 2. Model S dual motor gave you better range, better handling, better acceleration. Why is this not true for Model 3? Do you have...

Loaded 2018 p100d X. Anyone else getting this? Heated/Ventilated seats always says "COOL" even when the heaters are on. It use to switch between the two. Scroll wheel reset didn't do anything. Running 2019.20.4.1. Search function didn't reveal a lot, either. Thanks! N8

Seems odd to ask this in LATE JUNE, but here we are. It was about 65 degrees F today and raining. My wife got in the car and, because she was cold, turned the cabin heater up to HI. (Past 82F!) She was expecting melt-your-face heat, but instead only gets a very very luke warm air, if that...

Couldn't get much heat out of my heater today...not very cold out, but even turning it up to high on both auto and manual modes would hardly generate much heat. Finally after a long wait, got a little bit, but nothing like I'd expect for Hi and certainly not enough for wintertime. Anyone had this?

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.

I have heated my cabin 15min before I left home today. The outside temperature is -15C, inside cabin was -5C. When I drove not only cabin is warm but also no cold battery sign, and my regen brake acts normal. I left my car in the garage for couple hours , again cabin temperature dropped to -5C...

In my first month of a drive, I have driven 1400 miles. I drive in DC Metro traffic every day in this Nov-Dec Cold Weather. I noticed that my average power consumption has been 330 KWh/m. I drive about 22 miles one way and 50 miles round trip in a day with average time on road being about 50-65...

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...

How to access the heater assembly. Looking at the Parts Catalog, I'm guessing it's behind the glove box? I have to replace the PTC heater that slides in the assembly. Anyone here any experience with that? Thanks, Stu.

Get a 12v heated blanket! :p https://www.amazon.com/Car-Cozy-Patented-Trillium-Worldwide/dp/B0000DYVN9/ref=sr_1_3?ie=UTF8&qid=1543853558&sr=8-3&keywords=12v+heated+blanket

Very unscientific test. - I have a LR AWD Model 3 currently running on the 18” Aero winter package. - Most mornings I do the same drive - first I drive my son to school, and then I head down to work. The drive from my son’s school to my office in downtown Toronto is apx. 17.6 km (just shy of 11...

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?

I've been noticing the strangest thing with my driver's side window ever since it's been below freezing in my area. Most often during hard acceleration, I'll notice the driver's side window fogging. But only that window. The window will be fine as I'm driving normally, and then instantly fog up...

Obviously this is a personal choice, and everyone may have a different view, but now that the cold weather is starting to appear, and it will only be getting colder, just wondering what people have been setting their cabin temp (with the objective of minimizing range hit)? It may change when it...

I just got my first Tesla. It's a 2014 Model S P85+. It has the Tech package. It does not have the Winter package. I've noticed the heater isn't working. I've checked the fuses, these are good. It seems that the windscreen heater does work, but it's not strong. Thus, obviously I'm suspecting...

I've got 14,400 miles on my 3, and the lifetime power usage meter has been slowly dropping, it was down to 225 Wh/mile recently. But now that I'm starting to use the heater, the power usage is going up, it was at 227 yesterday! And I already notice the difference, having the heat on in the car...

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...

Noticed that when AC is on "Auto" the vents on the back blow warm air (even when temp is set to 65*) Took it to Tesla Service and they told me this is "normal". When I set the AC to "Manual" the issue disappears. Anyone noticed similar behavior?

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...

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...

I'm still new to my Model 3. Sometimes I notice that the car is heating (red user interface for the HVAC) when I really just want low AC. If I set the temp to 74 and it's already 73 then it seems to want to turn on the heater to change that 1 degree. There should really be a software toggle for...
