My electric windshield, 2006 ST, locks on right side, able to move it by helping it. Windshield moves about one third from the top before it stops, if I toggle switch sometimes will move all the way down without stopping, but now locks there too. I have cleaned and lubricated the tracks, no help. Any idea how to repair this, motor seems to work fine, left side moves fine. Thanks for any help you can provide.....
