window problem, need to know what it could be

I hope someone can help here. My passenger window is functioning properly. The issue with the window is: while the window is going down, half way through I hear a pronounced metal crunch. I hear this crunch even when the window is being brought in to the full close position. The window goes down at a normal speed, but won't go up as fast. The window is also loose, I can move it around. The situation occurs because my brother gave the door a jolly old whack - really was fierce.

Now there are plenty of videos on youtube and diy's walking you through the dismantling of the regulator etc. The reason for my post that I need to know what is exactly wrong. I would really appreciate if members can suggest what is wrong.

I would say a window regulator pulley is likely broken and/or the cable is starting to bind.

Time for a regulator would be my guess. The URO regulators are supposed to be updated with ball bearing rollers, some have had luck with these.

More than likely will be a window regulator, do not continue rolling your window down anymore because with that metal click sound you hear eventually you'll hear it again and the window will stop moving, therefore you'd be stuck with a non-functioning window. go get that regulator replaced asap.

So I should strip it down to start with, and then assess the situation.

You can certainly open it up to look, but your regulator is probably going. Just order the part, wait for it to get here and then do it when you receive it.

Common problem on the e46s.
