I came across this today. We've had this problem for a while now with our 2013 Fusion Hybrid SE. All 4 windows have exhibited this problem at some point during our 8 months of ownership. Has anyone has this TSB performed? http://www.fordservicecontent.com/Ford_Content/pubs/content/~WT/~MUS~LEN/3545/tsb13-10-04.htm
