[Weird humming noise]

I had the same problem on my 2007 Pathfinder, it was like a rattling or air sucking noise at about 2000 RPM. Turns out it was a loose clip on the aircon pipe.

 

What's the aircon pipe?

[Weird humming noise]

I have a 2007 pathfinder and have noticed a weird humming noise coming from either under the dash or under the hood. It does not happen until I get above 65 MPH and it is not constant and not all the time it starts then is stops then it starts up again. It seams like if I have someone in front of me on the highway it goes away all most like its just something vibrating in the wind. I also notice it happen more when its hot out. Its been doing it since I bought it and it only had 37k miles on it. I never take it off road and have only had it in 4x4 once. Any help would be great the noise drives me nuts.
