If you suspect a leaking seal, go to the petrol station, quid in the jet wash and spend a while just going round the seals, have someone in side, if nothing comes inside off a jet wash then its water tight. do the top of the screen, side, top door seals, and areal base.
Id sway more towards pollen filter, as when condensation turns to water, its going to run down the screen, not upwards, so explains the trickles of water.
