I am getting a wind whistle and I finally figured out where it is coming from. It is coming from the two center air / heat cabin vents, but it only makes the noise when the cabin "air recirculate"  button is pushed in on my 2002 Frontier. If I push the button on the left off (light goes off) the sound will stop. This is really odd. Any similar stories or fixes?

Check for any air leaks between the blower housing and A/C -heater unit??????

One thing I forgot to mention is that it starts around 45 mph to highway speed. The noise is not due to the blower fan as it whisltes with the fan off.

I have tested the window molding and as I drive and I have isolated the sound to the two heat / AC vents front center. When I press the recirculate button at between 45-65 mph it sound will start and stop as I press the button.

Again,with the blower on, check for any air leaks between the blower housing and heater/a/c unit.
