How can I fix my window switch that has stopped working properly?
My 2006 BMW 330ci has four window switches to control all of the windows. One slight pull on the front two window switches should make the windows roll all the way up. My driver window switch will no longer roll down my window but will roll the window up if I hold the switch. The automatic one touch roll up also does not work. If I pull the switch quickly to engage the automatic roll up, the window simply rolls up slightly and then rolls all the way back down. How can I correct this issue myself? I feel as though it would be an easy fix or a really expensive one at a dealership.
I have a similar issue. My driver's window automatic roll down doesn't work, but it works upwards. I've read that it's a synchronisation issue, but I haven't been able to fix it.

replace window regulator in the door. The regulator utilizes a plastic pulley, this pulley is the failure point.
