The Silverado, Tahoe, Avalanche, and Suburban of Chevrolet. The Sierra, Yukon, and Yukon XL of GMC. And maybe the Escalade(2002). The problem with these trucks is that they make a noise similar to a propeller airplane engine running at high RPM when the truck's A/C blower speed is set to high. Almost all these trucks do it. I experienced this with the Silverado, Yukon XL, and Sierra. of the years, 1999-2002.
No they don't, remove the blower motor and look inside the fan, I'll bet you have a small piece of leaf in there, you probably park under or near a tree..
