I have a 2010 F150 Lariat Super Crew. The rear sliding window does not completely close. I have read a few posts about lubricating the cable and tapping the window motor. I have leather seats with the rear arm rest, but cannot locate the window motor. I have lubricated the cable, on both sides while someone opened and closed the window.
I have attached a picture. The small metal crimp hits the black plastic stopper and the window is still open a crack. It is as though the window slid open more from its original spot.
Need ideas please.
