Basically pull of the door panel, unhook the regulator, then unhook the window from the brackets as the regulator and brackets are one piece. If the window is up its quite a ***** to unhook. Then put the new mechnism in and let the window drop a little and hook it up to the metal brackets. Just a little advice, make sure u look at the brackets still in the car so you know the exact positioning the metal wires are supposed to be in.
