Getting there. Front door windows next. We’d looked for some decent doors because ours need replacing, but had to settle for the windows only.
Like the rest of the glass, they are windy up ones, not sliding, so sorting out the scissor-style winding mechanism was something to contend with for the first time.
Remove door card. Then remove all broken glass (lots) from inside the door. Take out metal panel and winding mechanism.
Insert glass at an angle, ensuring ball rollers go into the track at the bottom of the glass. Again two pairs of hands are good. Three would be better and then there might be more photos.
