How to reattach Rear Glass Panel
 

I have a 2004 MPV and a couple of years ago my husband took the lawn mower to be serviced and didn't secure it and it took out the entire drivers side window at the rear (the quarter panel one). We paid a small fortune to have it replaced but now it is detached at the front part and his answer was to tape it. Does anyone know how they are attached and if they have to be glued? I'm ready to just do it myself but I don't want to mess it up more.

Thanks!

a simple silicon based window sealer will be fine.
