happens all the time.blocked sunroof vents.small circular holes in sunroof/bodywork recess corners connect to tubes that run down inside trim to vent under car.try wriggling small diameter semi stif wire down holes till it pops out underneath,the kind of stuf used by gardeners for tying branches back,or mig welding wire.or if u have acces to compressed air that sometimes works BUT air pressure can also blow the drain pipes of the stubs,NOT GOOD.
