Tesla will assign a charge for the repair when you make the appointment. If Tesla determines that the repair is covered under the warranty then your credit card will not be charged.I do have a second SC appointment pending at a different location for this same issue, but it looks like they want to charge me this time. The app is asking me to accept a 100.00 estimate for labor.
Is it possible to actually talk to the techs and show them my pictures and documentation? Last time I didn't get to speak directly to anyone, only texting online via the app. They just tried the AC 3 times and found it worked each time and declared problem could not be reproduced.
It's intermittent! That's why I'm trying to help by documenting it ahead of time.
Is there anything else I should record to demonstrate the problem and best help them to find the cause?
I was thinking perhaps a second thermometer measuring outlet air temp from the vents.
This may be useful especially since I just discovered today that the updated iPhone app no longer shows red and blue air to indicate heating/cooling respectively. Now it's just plain white. So that info is gone. Glad I got some pics with the old app.
At one time a mechanic would take a vehicle home, overnight, if they were unable to reproduce the issue at the service center.
It would be somewhat elaborate but you could set up a GoPro to record the thermometer as you drive. Eventually you would be able to capture the event on video.
[Years ago I drove a Saab 95. When the 95 was new, without any warning or changes made by me, the HVAC would start pumping out full heat to the rear seat vents. I must have taken my Saab 95 vehicle to be serviced four or five times, half a day each time. Usually I would remain in the waiting area while Saab attempted to repair this issue. Eventually the service department was able to identify, replace the faulty components and the problem never recurred after the final repair.]
