What is this high pitched cricket like noise?

Every day I hear this sound & no solutions yet huh

Have you tried stuffing some foam under the back seat bench … to test - pull up the back seat bench completely - there is one wiring harness for the heater - you don’t have to remove it - leave the seat folded down - drive around see if the noise is more pronounced - you can get noise cancellation foam and stuff it there and put the seat back to see if it helps. There are YouTube videos of how to take rear seat bench out.

No no one is really sure of the source rn and it difficult to solve and people arent willing to tear apart what might be their daily driver and figure it out

All My Tesla Model Y Repairs in the First Year and a Half - EVchargerReviews.net

My Tesla ownership experience has certainly gone through more ups and downs than anyone I know. Here are all my repairs from the first year.

This guy had the issue and got it fixed but he had to go thru hell to get it done as well

Chances are the issue will come back to him if they used remanufactured FDU. It seems like 2024 builds no longer have this issue.

That's penthouse seal issue you are talking about. It's quite easy to diagnose, compared to this issue.
