Noob here with a few questions.

I'm new here and I have a few questions that I couldn't quite find answers to searching the existing threads.
I drive a 2011 Tacoma TRD Sport Double Cab, Short Bed.

First, the hood scoop. Usually when I'm driving in windy conditions I hear a squealing/howling sound that seems to come from the hood scoop or the wiper blades. Has anybody else experienced this? I used to have an '08 Tacoma w/out the hood scoop and never heard this noise, which leads me to believe it is coming from the hood scoop. Am I just being sensitive to the normal air flow around/over the scoop? Or should I get this checked out? Thoughts/suggestions?

Second, the Air Circulation button. This seems to be happening more recently since the cold weather and I've been using the heater. I usually have the settings as follows: Air Circulation On, A/C Off, set for Foot and Defrost Vents, Low Flow (not Off), Heat set anywhere from warm (knob straight up and down) to Hottest. If I have those settings and run a little while, the Air Circulation light goes out after a minute or two, meaning circulation is not happening anymore. I can turn it On again, but it will go out in another minute or two, and usually repeat this process my whole commute (~1 hr). Why is that happening? Is it supposed to happen or shouldn't it stay On? This did not happen in my '08 Tacoma. In that truck, if I put Air Circ. On, it stayed on, even after restarting the truck. On this 2011, the Air Circ. goes out all the time. Thoughts/suggestions?

 

Press and hold the circulation button for about 3 to 5 seconds. This will keep it on.

 

Thank you. I did just find a relevant thread with the same solution linked below. I will try it out and report back. Hope this works!

There is a TSB for windshield noise at speed (NV006-07).

I have it, you might too. You can put some silicone around the molding to get rid of it.

Thanks again, guys. Holding the button definitely keeps it on and so far seems to hold the setting even after restarting the truck.

 

Thanks, I will start looking into this and mention it to the dealership next time I go in to see if they can fix it for free.
