Whistling noise which gets louder the faster I go. I can start to hear it at forty mph and then gets louder. It is coming from drivers side vent. The small one near the wing mirror.
Could it be a cabin filter leak or something?

If you open and close the re-circulation door does the noise change?

Went back out today. I know the sound can sometimes travel funny in cars. So I removed the inner cover to wing mirrors cover. Noise got louder so it look like the air leak is there. Will remove it at work tomorrow. Hoping just a bit of mastic only is needed.

You can try that make sure the mirror is also sitting flush.
