The factory rear seal under the windo is rubbish; it needs to be removed, cleaned up and sealed with new silicone. Any RTV will do but I used black.
This guide is the go.




What never happened on mine, so can't tell the potential severity of it, is that the third brake light can develop a leak as well. Maybe probe a finger behind the trunk lid liner, for moist in there.
If that is your issue it should be pretty obvious, if you shine a bright torch in there, under the window, where the sealing strip bolts on with a nut each side. If it's been leaking there will be signs of rust and drips of water around the seal. While you're in there check for water ingress, pooling around the roof pump at the bottom of the boot.
