1stcls550

I have an 08 cls 550. On occassions, when I roll the driver window down, it squeaks really bad-it sounds like there are "rollers" that are really tight and it only happens on the way down, not up. Usually, it goes away after 5 or 6 times of doing this, however it's been going on for over a week. Has anyone else encountered this, if so what's the fix? If not, any suggestions? Thanks in advancce
