I believe they are called louver windows, and they are being used more on the high end units today, if they have a rubber seal, the rubber tends to deteriorate and stick to the glass, the same as the windshield wipers, you might try getting some of the fluid that is used to mount tires, you might be able to get some from the tire store, take a mayo jar and ask for some, put a little on a rag and wipe the seal so hat the window does not stick, this is a rubber lubricant, you can also spray it on the rubber mounts from the shocks when they start to squeak and he sway bar bushings.
On the crank mechanism buy some 3-in-1 oil and put a couple of drops on the crank and hinge at the tops.
Do not use WD-40, it tends to collect a lot of dust very fast and leaves a grey residue on the long run.
