Wind Noise

I drive my wife's Enclave on the weekend. She said she noticed that there is more wind/road/??? noise on her side than the drivers side (front seat). I sat over there and she is correct, there IS more noise on the front passenger side than the drivers side but I can't tell where it is coming from. I checked door/window seals and can't seem to see anything that is obvious. Is anyone else hearing the same thing on the passenger side front seat? It is not extremely noisy but it is noticeably different. Thank you in advance! - Jason

Enclave CX, sunroof, NO wind deflector on sunroof or windows, no cross rails on roof rack. Wife loves her Enclave! - approx 2000 miles thus far.
