Since I bought my 2008 GS350 AWD with 112,000 Miles on it, I noticed a wind noise that would come from what seemd to be behind the stereo unit.
Only happens when driving and it would be more prominent the faster I drove. No heater/AC fan on no music on so just the wind noise coming through.
Thought it was from air recirculating option so switched that to both settings - still same issue.
Wondering if the car has some sort of noise filter going on or is this a bigger issue?

 

Sunroof weatherstrip? That was the fix for me.

 

Hi 👋 im all so having this problem it's probably coming from the ac I hope the dash don't have to come out to fix it

 

What makes you think its the AC? Even if system is off this noise occurs on mine.

 

I get this same noise too when my ac is off 🤔 so it could well be the flap doors that opens and closes and one of them is not closing all the way shut this is what I believe if it is then the dash got to come out

 

Try slightly tilting the sunroof up/down to see if a different seal quiets it down. If AC is off I don't see how wind would be coming from the dash. Blower isn't blowing any air.

 

Could also check to make sure you’re not missing any body plugs in the underside of the car. They can cause extra noise.

 

I will try this option. Just need to wait for it to warm up a bit don't want to chance busting anything with the extreme cold up here.
