Recently my 94 explorers drivers door window crank started skipping when the window gets to the top and is almost closed. I figured the splines in the handle were toast so I removed the handle and they look fine. I took the rear door crank off and swapped to confirm and same thing happens. Following weekend I took the door panel off and looked down inside the door and can see the gears are skipping under any tension. I guess I have to replace the whole works? window lifter and everything? It seems like everything is kind of a "sealed unit" like there is no way to take it apart without complete window and mechanism removal. It's snowing and I would like to be able to fully close my window without having to push it up by hand Any help or links would be awesome.
