Postscript - I've learned more about the red button mode for the defroster, and am posting the following in the hopes that others can avoid my difficult experience.
In calm circumstances, I set the defroster on red, and observed that the fan was blowing 'room' air, which was what I experienced on that dark, cold, snowy night.
I made an appt for service, and today when I picked up the car, I was told that the defroster didn't work because the car was in 'range mode'. I could find nothing in the manual that suggested range mode controlled the defroster, so I did a little experimenting and learned that the defroster does work, but that it takes 4-5 minutes before delivering any heat (with range mode on). I also confirmed that the defroster takes about the same time to deliver heat with the range mode off. (In hindsight, I wasn't patient because I had very limited visibility in difficult winter driving circumstances and my expectation for defroster heat was influenced by the cabin heater delivering heat in about 30 seconds).
With my experiment conclusions based on an n=1 test, I'd be happy to learn if others have same or different results.
To summarize my beefs with this car/Tesla,
- either expedite the delivery of defroster heat (red button) or document that it takes 4-5 minutes to be effective
- add an AM radio
- provide a user manual in RAM
- add a rear windshield wiper/washer, and a washer for the rear camera
- embed a heater in the front windshield for the wiper blades
- when stationary, permit the wiper blades to be removed from contact with the front windshield
This strikes me as a very reasonable ask for a $100,000 car.
How does one get this information into the Tesla engineering dept?
Thanks to all of you who have contributed to this thread - I've learned a lot, and now know to be patient when using the red button mode for the defroster.
