I have a 2001 V6 mustang convertible. Last month the passenger window and the little back window on the passenger side as well, starting malfunctioning. The front window button wont put the window down but it willl put it up, the drivers controls can put the window up and down. The little back window will go down but cannot be put back up. Does anyone know whats going on? And how do I fix it?!!!!?
Tks
