Good morning, I have a 1999 saturn sc2 and the driver side window will not roll down. How do I do first?

broken shifter bushing. these bushing kits are sold on ebay and at parts stores for about 20 bucks. have to remove the console. how to videos on youtube.com

Either the seal around the glass is dried out/shrinking, or the sunroof drains are clogged.

Hi, You have three fuse panels/boxes on your Saturn. One uner the hood (drivers side) One each in the front kick panels the identification is located on the inside of the cover. The lighter fuse is located in the underhood fuse block. It is a yellow 20 amp fuse lay the cover next to the fuse's then you can identify where its located in the panel Hope this helps

SWITCH COULD BE BAD ALSO THE WINDOW COULD BE IN A BIND OR OFF TRAC.MAKING IT HARD TO GO BACK UP.

you need to have the actuator replaced. While you are at it you may want the other side done also. If you think you can do it on your own, its not a tough job but that is the problem.

REPLACE THE POWER WINDOW SWITCH

Remove the door panel and find the window motor Unplug it and using a separate car battery run cables directly to the window motor When you switch the polarity the motor will either bring the window up or down or if noting happened change the window motor and window regulator assembly.

HTH.

Sounds Like you need a window regulator! Can you still hear the motor running?

Is it antifreeeze from heater core or heater core hose leak?  Is the leak pure water, or maybe something else?
Put it in the garage again overnight with an old white towel in the drivers foot well, best if you can find a way to stretch it from drivers seat forwar to firewall and keep it off of floor mat.  Check it before you go to bed,  then in the morning if no leak found yet.  see if the color/location of the spot helps you identify the source.  I think the heater core is under the dash center.  Anti freeze is green/yellow or orange.
good luck
