Most often on those the motors are shot. as soon as they are activated they overheat and slow down or stop. Only way I know of to repair is to replace them. You will need a manual to do this or do them one at a time so you can check how it goes back together by looking at other one. Motors are riveted in and need to be drilled to remove...use small bolts to re-attach.
I've seen motors online for about $30-40 each.

Does it try to come up, EG is there power being applied when you press the UP switch? if it makes no sound or movement when pressing the UP switch it is probably a worn out switch - available at Pontiac dealers though you may have to order it and wait a few days - have your VIN number for the parts desk and you'll get the part in no time - the switch levers out of the panel - use a plastic tool if possible to prize the switch out so you don't damage the surrounding trim - the cable connector clips off the old switch and goes on the new switch, press the switch home into the recess and jiggle it a bit to make it dead flat - window should work now.
If it IS making an effort to come up then either you have a poor earth or power connection making it so there is not enough power to pull the windows up (which is harder than down due to the weight of the window) -- check the cabling behind the door panel, and as above pull out the switch and check its connector too.
OR... the window is out of alignment and is jamming - putting it back in alignment means taking off the door panel and getting at the bottom of the window runner, loosening the bolt(s) on the bottom of the runner and moving it sideways so it hold the window steady but not tightly, you may have to try having it tighter or looser against the window till you get the best performance - also oil the moving parts/cables of the window mechanism (dont get oil on the glass, it will smear for weeks) to give the best chance of smooth operation.

Two things can be the problem,first,try adding ,a little freon,if it is low,it will only cool one side,then if this does not help,there is a door actuator motor that controls this,it could be not working,the dash has to come out to replace this actuator motor,if this was at all helpful,please rate,thank you.
