I solved problem, It started with my first 1998 Holiday Rambler Endeavor. My wife did squeeks and rattles for Ford motor. My hearing was not real good so no noise for me. She went around the coach found the noise. Orders fix the noise, found that the gizzmoes that fit in the drains were gone bought some they would not stay in place and lost more.
THE FIX clean window area around opening a LITTLE DAB of clear silicone on new part will hold in place never lost another after the fix, drove it for over 120,000 miles. Never heard about wind noise again wife very happy
