More than likely you have a blocked drain tube on the evaporator, when that plugs up, you'll get water in the cabin. Here's a thread showing its location, you can take a bit of stiff wire with a hook bent on the end and carefully(really carefully!)fish around up there to clear any debris, insects love to build nests in the tube. Give this short thread a look, pics of the tube location included.....
Another thing is to remove the cabin air filter to check for leaves and debris clogging things up from the inside.
