I need some help =\ my drive side window keeps jamming half way up and goes up and down really slow.... Does anyone know how to fix that or a write up on how to fix the problem?

 

I would start by removing the door panel and greasing all the moving parts related to the window including the window track. I had to do that on my XJ and it did clear up the problem. The other thing (hopefully not) that can be wrong is the windo regulato motor can be going out.

 

Everything is all lubed up, the window goes up a lot faster but still pinches about half way up and makes a sound
