When I start up my CT in the morning, very often there's a very obvious clicking sound coming from the vents/fan (both heat or A/C). I turn it off and it stops. If I keep it on, it generally stops in about an hour, then it's often good for the rest of the day. This is the only pattern I've found so far. It sucks because Tesla explicitly says, if there's a noise that you're bringing your car in for repair, and the noise is not present during your appointment, there's nothing they can do, which is understandable. So I've been trying to keep the fan off, and then turn it on mid-day, so I can replicate the issue when I bring it in to Tesla... Then today, I found the center console on the windshield with the gear shift and hazard button started making a similar clicking sound, not as loud and it stopped in under 5 minutes. Anyway, thought I'd throw it out there and see if anyone else is having these issues?
