Ventilation dead

[m0rph]

New problem, my interior ventilation blowers seem dead. No airflow, no errors. 0, 1, 2, 3 airco on/off nothing.. I checked the fuses, they seem fine. Damn, I can't survive this humid weather without them..

Check fuse?

My guess would be a corroded or blown blower resistor pack after you've tested the switch is functioning as it should:

HVAC fan motor not blowing air at all. A/C Motor still turns on though - LotusTalk - The Lotus Cars Community

I have a theory, I suspect the 12V battery. Over the last 3 days, I hardly used the car. Normally it gets a good workout every day without exception. This morning the battery showed 12.4V but after a few more kilometers it went to 12.6V and the blowers were working fine again. Before it always showed 12.9V. Tonight I'll hook it up to my Tecmate Optimate 4 so it can recondition it and recharge to max level. The battery is 13 months old but also has 70000km of experience.

Have to love it when its an easy fix! Tesla really should throw a warning when the 12v battery drops below a certain threshold and mention that all 12v accessories may act wonky until its resolved.
