    I have a 97 Chevy P/U and going at freeway speeds I get pop noise from blend door area and air volume changes back and forth while on freeway. I don't notice in town but I have notices slight air volume change in town so I think it happens all the time. I don't know where to look:neutral: I am looking for some suggestions out there would be helpful.
