I want to remove the front door panels to upgrade speakers. I booked it in with halfords and the guys didnt know what they were doing and put it all back together. In the end the window was malfunctioning and would stop half way and would stop working and then after few minutes it would work. Kept getting stuck or stopping. It all works fine now. I want to replace them my self but im scared that same thing might happen. Is this something to do with SEAT or do windows reset or anything like that? i dont understand why the windows were acting weird. Can someone advice me please on how to proceed with this & also which speakers to go for ?
