Window gets stuck closing/opening

On my Z3, I was working on fixing the window getting stuck by greasing all the components. However, for some reason, after greasing everything, it still gets stuck.

Here’s all the components of the window regulator that I greased:

Here’s a video of what’s going on:

It also makes a weird squeak sound when going down and I don’t know why. I have to spam press the up/down button to make the window go up/down.

The tracks or track runners or sliders, are probably the cause... Never had the problem with my Z, but many cars I have had has. Spent years as a professional driver with windows going up and down 100 times a day...

try a bit of silicon spray on the rubber window guides , if not silicon try wd40 or even washing up liquid
