    My 07 silverado LTZ 1500 ext cab makes an odd noise when only at highway speeds. Sounds like lips smacking together just outside the front windshield towards the upper portion. Anyone else have this issue?

    Wow did not think of that. I've had other trucks with deflectors and never had this issue. I think you are correct though.
