My Explorer was broken into on New Years and the vent window was smashed out. I had a quote from a local glass shop for $180 cdn for the glass and replacment. I aquired a new window from a local wrecker for $40 cdn. This was my first time doing this and the job took 1 hour with no special tools. 1) Here is what I started with. You can where the exterior trim is bent from where the window was pried out. First thing was to clean up all the glass and clean the weather stripping out as there were lots of little pieces trapped. A flat screwdriver and the shopvac were used for this. 2)Remove the interior panel. A flat screw driver and prybar were used to pry out the clips. Next peel back the plastic dust barrier that covers the door. Remove the bolt that holds the window guide. It is the yellow plated bolt (11 mm) visible in the picture. 3) With this loose you can pull out the weather stripping for all around the vent window and about half way down the door on the upper seal. This is where I was able to clean any remaining bits of glass out. 4) Install the window into the stripping. Slide it into the vertical channel first and then mold the flexible portion around the window. Install the window sarting at the top and work the weather stripping back into place. I found it easiest to stand on the outside of the door and push the lip through to the inside. I used a flat screwdriver and needle nose pliers to get the rubber back into place. Just carefully work your way around without putting too much pressure on the glass. When the window is in push all the stripping back into place and reinstall the bolt that holds the window guide. Put everything else back together and you've got it completed!
