When I got my 90 900 T, both windows were "dead". The driver's side could move down maybe 3mm and up 3mm. I removed both window mechanisms and motors. Thouroughly cleaned and greased the regulator mechanisms, WD40 then white lithium grease. Then put the motors direct to 12v power. The d/s one spins nice and fast, the p/s side doesn't actually move unless you grab the gear with a pair of pliers and "help" it along. I disassembled the p/s gearbox, the grease was solid and the shaft had rusted to the "bearing" at the end. I took it apart, cleaned it out and put new grease. Now it spins nice. I installed everything. D/S window went down poorly, and wouldn't go up. P/S window worked fine. Replaced the power window switch, which did bear signs of coffee spillage by a previous owner and some corrosion on the spades. Now both windows work very very well. I also had a problem on my 90 900S with a dead sunroof. Just for fun, I put a rear power window switch of an 1988 car and plugged it to the sunroof connector, sunroof moved back and forth very nicely. The switch contacts over time will get dirty. You can clean them if they are the older (not integrated) style IIRC. I've never actually done it since I've always had a bunch of switches lying around.
