Just bought an 01 Suburban to pull my boat with. I've had a 00 Silverado for several years, so I am familiar with the Chevy ride and all. But, I am getting some kind of noise from the Suburban. It sounds like it coming from the widshield area, and only starts at speeds over 65 mph. I thought t might be the wind passing over the wiperblades.. Don't have this problem in the silverado and I hope I can fix it on the suburban as it is going to irritate me all the time now. Anyone else had this problem and figured it out please help.. Thanks
