It seems like the higher setting of the fan bloewr, the colder the air coming out!
Try this and let me know, set heater temp to Hi, set fan blower to 5, wait until air us hot, now set blower temp to 10, wait a minute or 2, air blowing cold!?
If you try it, let me know before I schedule a service call...thx

There is a technical Service Bulletin for this very issue that was issued yesterday. Schedule a service appointment and they'll replace the sensors.

My car was at the SC in Oakville Friday of last week. They claim they replaced all sensors (all 3 of the, he said).
What a waste if time. I own 2 teslas, never brought any if them to the SC and git the issue fixed. I learned to live with Tesla with issues!
Oakville SC in Ont. Canada is the worst.

XY2B - My heater blows cold sometimes also. I'd like to try your experiment, but I'm not sure what you mean by setting the "blower temp to 10". If by "10" you mean 10c, then of course it would blow cold. Could you clarify this?
