whistling noise inside cab

[fowl mouth]

This is my first time posting at this site.I have recently purchased an 05 explorer and there is an unusaul noise inside the cab on windy days.I do not hear this noise all the time but when i do, it is very annoying.It sounds like a kazoo and seems to be coming from the passenger side.I am sure i am not the first person to experience this problem. If anyone can tell me what the problem is i would appreciate the help.

i would check the passenger door rubber and/or the pass window rubber....the reason you only hear it on windy days is because that is the only time you get wind from the side...
