Model X no heat

[Jillmark99]

Hi all
Woke up this morning and all of a sudden my X has no cabin heat. I have read online that people have had issues with an electrical connector for the heater. I assume they mean the electrical connection for the heater core. Can anyone tell me where that electrical connector is located? I would like to check it before having to schedule an appt with service. Thanks in advance.

Contact Tesla. They can often diagnose issues like these and sometimes correct via OTA updates.

They might be even able to send out a Ranger to correct it.

My X has done that multiple times - heat just quits working. A reboot by holding down the two steering wheel buttons has always brought it back to life.

I got the new 2021.4.3 update this morning and my heat wasn’t working well (blowing cool air when set to HI) when I took it out for a drive (it’s in the mid-20F here today). After about 15 minutes, my screen went blank and rebooted itself (no help from me) and my heat started working fine. Either a happy accident or a smart car.

My heating unit in my 2016 X was broken in autumn 2020. I waited a couple weeks for spare parts.
They also changed the fuse unit in prevention because a lot of work to change it later.

I’ve already tried a reset as well as a full power down for over an hour. No dice. Still no heat.

Things like this are why I always fully reboot (brake down + steering wheel buttons) after an update. After adopting this policy I not experienced any of these "just updated" issues.

Sounds like it is time to get it into service.
