Just take off the door panel and try to spread grease in the tracks where the bushings ride, at the pivot points on the regulator, and anywhere else where it looks like something touches something. Taking a flathead screwdriver and spreading a little grease in the window track, all the way down into the door, may help too. If you get the panel off and get it moving, the places to grease will be a little more apparent.You'll probably have to grease places and "help" it up and down as you grease somemore. As you do this, it should get progressively better. If it has a 2 stage regulator with the power wing window that goes down first, there is quite a bit of places that can be greased. The wing window also makes it harder to remove the regulator, which is why I haven't fixed my TC, I just greased it and got it working good enough. Its not bad, just a little slow.
