Wind noise in 2005 Tacoma

My 2005 Tundra has some noise from the driver's side rear view mirror in a head wind. But it doesn't bother me. Also, my 2000 Saturn LS1 has the same thing, it's a little more annoying, but again, I don't let it bother me.

I have the exact same thing. On a windy day I heard it for the first time and thought is was an alarm. It was annoying but intermittent. Does your truck have the scoop on the hood?? Wondering if that had any effect. It is always the same pitch.

I also experience the exact same thing whenever winds are higher than normal. A high pitched whining note that seems to emit from the dash area (my guess is the windshield seal is defective somewhere). Drives me nuts, especially since everything else about my 2005 Tacoma is above satisfactory. Heading to the dealership when confidence is high that the sound can be reproduced. P.S. Don't have a hood scoop.

I also don't have a hood scoop. I looked under the hood and noticed some small holes in the center of the firewall just below the major air intake. I put a piece of tape over them just on a trial basis. It seems to greatly reduce the noise and it doesn't seem to have changed the airflow to the interior any.

But I won't know for sure if this is it until I get a chance to try it in some really high winds - which shouldn't take too long here in central Oklahoma.

I had the same noise on my 2005 Tacoma Quad between 65 and 75 mph depending on the headwind. One thing I noticed is that when I turned on the windshield wipers the noise stopped about half way up the windshield started again about the top and stopped at the mid point on the way down.

I made two changes. 1.) I noticed the factory wipers had slits in them ..I'm betting the noise came from there so I swapped out the wipers for a more open design with no vents.

So far so good. I've only been on the highway once since making these changes but I got up to 75-80 mph on a windy day for about 10 minutes and no noise.
