Rear side window coming loose (3door)

Hey!
The bottom part of the RH rear side window has started coming loose on our 3 door Micra. How can this be secured again please? Is this fitted with adhesive, or somehow with a rubber seal underneath?
I couldn't find much about this through google or in this forum.
Any help would be appreciated please.

Many thanks!

Dan
 
Photos would help, is it literally peeling away where you can pull at it and open it like a cupboard?
It is peeling away, so it'll rattle when the door is shut with the windows up etc.
I took a photo, that's at the bottom corner of it at the b pillar.

I have no idea how to solve that sorry, have a look at this link


So I guess its got rubber between the glass and the chassis, and maybe the rubber sits into the window hole like normal, and then the window is glued onto the rubber? Which would then probably mean you need to look at some sort of glue/sealant, or have a google at parts numbers, look at 3 door rear windows on ebay and see if you can tell how they were attached
