If I lowered the driver's side window while driving, when I put it back up there would be a 1/2 inch gap at the top, allowing rain in and creating lots of wind noise. I removed the interior door panel and found a bolt, holding one of the "scissor" arms, loose. I tightened it and fixed the problem. Of course, now I am having the problem of the non-functioning driver'as side window--a major nuisance when I have to show my ID at the gate at work and at the drive up window at the bank.
