I've read about this in other threads. Just started getting this today. There are numerous fault messages visible under service. No heat, can't turn climate on remotely and can't use Climate Keeper either. I've tried the thumbwheel reboot process. Also turned the power off and after 3 minutes woke the car up. We also just had a software upgrade a day or two ago and now this problem. Any ideas?

Thanks. Got into service mode, ran the HVAC test, and did get a Fail notice pointing to PTC Heater reports internal fault.
That's unfortunate, but expected. If you have Tesla repair it, the new repair process should be about 1.25 hrs of labor ($175 US x 1.26 = $220.50 US) plus $550 US for the heater, and $13 US for the service kit, so around $783.50 US. You don't need the diagnostic time since you did what they do already.

If you want to tackle it yourself, this is the repair procedure:


And the parts:

Yeah. I'm usually up for most automotive repairs, but perhaps not those involving the HV power lines. I did watch a video of a guy replacing one. Relatively straight forward. However, I have talked to the closest Tesla service center (7 hours away) and that's still an option.

Thanks for your suggestions, though. I now know a bit more about the car.

We just got a quote for nearly $4000 CDN dollars for our HVAC issue. Our Model 3 climate system has failed this morning (approx. -15C this am in Ontario) and the service department can squeeze us in, but to pay that amount seems crazy. Our car is less than 3 years old. Service department says the warranty stopped at 80,000km so we have to pay. Any advice?

There's also the cost of a new desiccant bag, although that's minor and there may be the cost of refrigerant if it leaked out or is contaminated and can't be reclaimed, although that may be minor, too.

Perhaps Tesla is assuming a worst-case scenario including replacement of the Supermanifold as well, which may not be necessary resulting in a lower actual repair cost.
