Abstract: An improved window assembly of the type that has a molded frame adhesively joined to the flange of the vehicle window opening includes means allowing it to be easily removed without significant damage and with access from only interior of the vehicle, as well as to be reinstalled easily. A cutting wire held in a groove surrounding the location of the adhesive bead has its terminal ends accessible from inside the vehicle. To remove the window, the wires are pulled from the interior of the vehicle, pulling the wire from the retention groove, past a flexible adhesive dam, and cutting completely through the adhesive bead. The window assembly may be combined with removable and reusable mechanical fasteners to both temporarily retain the window assembly as the adhesive cures, and to be reused to reinstall the window after its removal.
