Driver power window problems

Hey I was wondering if any other fellow saturn owners had problems with the power driver side (and passenger sometimes) windows going down when the outside temp. is cool or if there is precipitation? My 97 sl2 front windows sometimes struggle to go down at night when it's cool or if it rains or snows (im in colorado and it's snowed this month 5 times), but not in sunny weather. Any insight from the wise would be more than helpful.

Take a look at TSB 03-T-05 (I hope I quoted that correctly). Does this sound like your problem? "Rear Side Door Glass Will Not Go Up or Down, or Will Fall Down Unintentionally (Replace Window Glass Sash Bar Slider)"

According to the TSB, the window regulator is made of plastic and can crack causing the slider some grief.
Part number for the regulator is P/N 21172105.

Note: the TSB describes the condition with a rear window, but it could possibly happen to the front windows as well.
