Thought I'd provide an update on this... Turns out it was the driver side AC condenser fan. After a few minutes of running, it always developed this loud "cricket" sound.
The Fremont Service Manager couldn’t hear it, declared it as a “non-issue” and showed no motivation to fix it. After multiple complaints, a technician volunteered to “blow-out the bearing”, but that made no difference.
Last week I had the Frunk out in search of a different noise (which I was able to eliminate). While doing so, I realized I had decent access to the AC condenser fan shroud from behind. Since I could not see the fan itself, I decided to soak the fan core with WD-40. After all, what was there to lose at this point?
Well, it seems to have worked. I have not heard the “cricket” noise since. The fan is now almost as quiet as the one on the other side. Let’s hope this will last!!!
Its just sad that I had to figure this out - not the trained techs during Warranty…
