Hello, my driver side power window lately has stopped working it goes down ok but when going up it goes to about the top then just stops and makes a kinda banging noise trying to go up into the seals and it cant i need to use my hands to help it into the seals.
I have pulled the trim of before to see if i can see the problem but i don't have any idea what I'm looking for. any help would be appreciated.

Thanks.
