For several months, I have been hearing a chirping / gurgling noise when the AC is on. When I turn the AC off, it goes away. I have also determined that it is not the fan as when the heater is on with the AC off, the noise is not there. It is not very loud and the radio easily masks this noise. Nevertheless, I plan to have it serviced soon in hopes of resolving it. Has anyone else experienced this noise on their 2019 ES350?
they do not want fix.just pull other es model if they making noise when ac on.dealer tell you normal.i had this problem. And with dealer loaner car.loaner make ac noise.out es model has 2 origine. One japan .other one usa.i am not telling made in us model are bad but they just dont have good skill as japan factory .once again you need stop afew dealer to fix this problem.
i think i can fix statement. But not ac leaking problem my self.
i hope you fix ac leaking problem. Good luck

HVAC Noise
Also I found this video of the noise online https://www.youtube.com/watch?v=qD9bHLRtrxU which happened to be the same as mine. Can anyone confirm this is the same sound to cause the issue? Thx a lot!

This is very similar to the noise I hear intermittently. It's frustrating to not be able to demo this noise to the dealer as it occurs intermittently. I had an appointment at the dealer but the day and time I went in, the noise had stopped. It has not gotten worse - but it has been there for months (I have a 2019 ES). Because the noise is subtle and intermittent, I am concerned that it may be a while before I can get the dealer to even acknowledge the issue never mind actually resolve it. I am hoping that some one on this site would provide a solution based on their experience with a dealer. I certainly will provide my experience should I get it diagnosed.

I went to my dealership today. Unfortunately, they could not find anything wrong or abnormal in my car, since the boiling noise was gone today. And they refused to take a look at the solution OP posted earlier, saying that different cars have different problems, spending over 3 hrs on inspecting the car, pretty much the same as pre-delivery check, including bleeding all the fluids to see if there's any air bubble. I guess I'd just have to wish the noise would not come back again....or could be reproduced at the dealership

Since I read this thread I have been paying more attention each morning. Today, I actually heard the faint sound everyone is talking about. I can only hear it when the music is off which is probably why I have never heard it in the past. Every time I turn on my vehicle the first thing I do is pick a playlist to cruise to. While the vehicle was on I turned the air off and on a few times until the noise disappeared, really disappointed in the quality of Lexus.

Same issue here - disappointing
I have the same issue. Second reason I’m disappointed with Lexus. Think it’s a defect but hoping it doesn’t affect functionality. Good thing I bought the extended warranty. (First reason is brakes squeaking)

My 19 ES 350 is making the same noise as the youtube video linked above. Is there a TSB or a fix out for this that I could point them to?
That youtube video says: "UPDATE: There is now a fix for this. Just tell your Lexus service and they will know what to do."
