Hey I have been curious if anyone has had issues with the koup doors and windows icing up. I thought about this before but this morning we had some snow/rain and the window did not roll down that little bit. I had issues with this before when I had battery disconnected when i installed my amp until I rolled window down and back up again, i assume the car thought the window was already down. But if the window is stuck up it will bind. I have noticed this morning but my worry is me not noticing one day and go to close door and window breaks. If you have a forte5 you might not know what I'm talking about. This morning i scraped the window then pushed it down and no problems.
