The question you ask is too involved for a proper answer. You may want to go to a car parts store, or book store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
First of all, I had to remove the door panel by removing the door handle and by removing the torx screws that secured the panel. My Focus has manual windows, so I had to remove the window crank. This is held in place by a clip which is similar to GM vehicles. There is a white plastic pin (about 1/2" in diameter) that has to be removed from the window regulator. This single pin holds the window in place to the regulator. It takes some "playing with" to get the regulator in the proper postition to remove this pin. It removed easlily for me. In addition the outer molding on the outside of the door at the bottom of the window space had to be removed. This just pulls off. In addition the window rubber had to be partially removed from the rear side of the door (towards tail lights) and from the top of the door. Leave rubber hang leaving the rubber attached to the front side of the door. Obviously make sure all broken glass is removed from window track and rubber. We installed new glass by inserting it from the interior side of the door. It was installed at an angle without forcing. It was frustrating and it took some manipulation to acheive the proper angle. Once the proper angle was acheived the window easlily slid into place. At this time the pin was reinstalled through the regulator. I had to find the proper window heighth. My wife had to wiggle the window so the pin would slide properly through. After the pin was securely in place the door rubber was reinstalled with the window in the "down" postition. After this the door panel and molding was reinstalled. If there are any other concerns from you, you can contact Ford or consult with a repair manual or you may email us.
