cabin heater

Let's say I got a 1 hour commute to work in the winter. Which of the following would be more efficient? (by efficient I mean minimize power draw, as well as minimize wear and tear on all components) 1) Set comfortable temp (say 20 C or 68 F) when I get in the car (or a few mins prior via the...

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...

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...

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...

When I bought my Model 3 in early 2019, many reviews and general discussions claimed that the Model 3 relied on a novel method of generating cabin heat: The claim was that they scavenged waste heat from the electronics and motors; and if more heat was needed than would normally be generated, the...

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...

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...

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...

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...

As we get into colder weather here in the northeast, I've discovered an unwanted aspect of keeping my (new to me) 2013 MS plugged-in in an unheated garage: it seems to want to waste electricity heating the cabin even when I haven't called for heat via the app. I spoke to my local service center...

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...

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 240V@24A it...

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...
