I have installed the replacement regulator with motor. The only problems I really had was pulling the new inner plastic sheet down inside the door and getting the spring clip onto the front plastic roller. I ran an elmers glue stick across the top of the new plastic liner and after trying several positions of the window managed to get needle nose pliers in place to get the clip firmly in place. Somewhere, I read there is a procedure for stopping the window from dropping every time you lift the door handle. When that is sorted and I'm happy with any adjustments, I will be putting everything back together. I can't thank this forum and it's members enough........now for the sunshine!
