47-55.1 power window problem

[nvrdone]

OK, today I went back into the power window problem. All pivots, cables etc are lubed and the glass channel is clean and lubed. I removed the glass as recommended previously thinking that the glass may be too heavy for the motor. There are no springs in the system. The switch is wired directfrom the battery to the motor with an in line fuse. There are no relays for anything in the truck. I did find a slight kink in the glass channel which I fixed. I also bypassed the switch and went direct power to the motor.
After all this effort the right window which I've been working on does not move up any faster than the left on that I haven't messed with. I'm now thinking that the motor just isnt strong enough to move the glass up as fast as my new cars which is what I was hoping for. So I guess I just leave well enough alone.
Thanks for all the input.
