RE: Power Window Motor
Before you start tearing door panels off and replacing motors and tracks, try the simplest and cheapest fix first.
Ford has issued a number of TSBs and service messages all advising the same thing-- window glass channels must be lubricated regularily with a silicone based lubricant to avoid binding during travel.
Buy yourself a silicone based spray (WD 40 will do in a pinch) and saturate, I mean saturate, the felt in the window channels. The rear one is easy; the front one requires spraying downward into the door. Roll the glass up and down a few times to spread the lubricant onto the lower portions.
See what happens.
