never had to replace the window in a starlet before but I've replaced a few others. its not that hard a job take the door trim off and get all the old glass out (i used the hoover at the petrol station haha) get a new window, theres a simple mechanism inside the door that should be easy to work out. last 1 i did there was 2 plastic blocks on the mechanism and 2 holes at the bottom part of the window you dont see and they clipped in there and that connected it to the regulator and held it in place.
