Alfisti,
I have never seen a weak motor in any power window system. I have
serviced many.
Three things stand out from my experience:
1 - every time I get into power windows, there is dried up or worse
sticky, grungy grease in the mechanism. I have seen this in both the
plastic cable (or bead) and sector/pinion systems. Disassembling,
cleaning and lubing with white lithium grease is the major repair. Of
course if anything is broken that needs to be remedied.
2 - I always clean the electrical connectors in the door with a jewelers
file and/or medium sandpaper. I use dielectric grease upon reassembly
3 - Checking voltages at the door has led me to switches with high
voltage drop (burned contacts?). I am rarely able to disassemble and
clean them but I always try. If they come apart without breaking I can
usually get them working again.
I do not recall lubricating channels. I do not consider silicon spray
or WD-40 to be a permanent lubricant.
I did 4 windows in my wife's classic Saab 900 this past summer in about
2-1/2 hours. The difference is incredible especially considering it is
a 27 year old car.
The GTV-6 never got bad because I serviced it not long after I got it
while chasing a wiring gremlin.

In my experience no amount of lube will overcome the weak motors. As a friend
once told me... Just be grateful that they close.
