Rear window leaking inside

[Bobbymc]

I noticed this morning that when I drove off the back window was covered in water so I used the rear wiper to clear it ,then I noticed a few big trickles of water on the inside of the glass ,so I stopped and had a look and there was a small amount of water on the parcel shelf so clearly I have a leak,any help out there or anybody else had similar problems

Are you sure it isn't condensation. Hot days cold nights.....jus the right conditions fo condensation to form.

It's now happened for the 2nd time this week,definitely not condensation, seems to be coming from top of the screen directly below rear brake light area
