Error code:THC_w0016 , and Tesla service?

Bought a used 2020 model X, very happy with it so far but finally ran into my first error message. Air conditioner stopped, restarted intermittently, but now seems dead altogether. Does anyone know what these error codes mean or how I can find out more information? I see the manual has some codes but not all. THC_w0016 and MCU_w097 if that means anything to someone. https://i.imgur.com/eN6VJeR.jpg

Second any thoughts in general on what to expect for service appointments? A bit disappointing to schedule an appointment one week away and then get a message that remote diagnosis will take more time with the appointment pushed out a few days. Also tried asking service if the car was at least ok to drive, and they (somewhat understandably) just answered they don’t know without the remote diagnosis but to call roadside if it feels unsafe.

Does it seem like it could be an unusual problem if they can’t quickly diagnosis the issue, or is 5 days plus usual just to get error code feedback?

And sorry but any feedback on what to expect at my actual appointment would be helpful, my concern is I will have to wait 10 days just to be seen and then find out then they have to order a part and schedule another appointment 10 days out, with me not knowing at all if I can even use the vehicle without further damaging it.

Any feedback or thoughts appreciated!
