I still think you have a windshield leak. You said you find water there in the AM before AC has been used. My windshield leak came down by the right hand fuse box also. Especially in the winter. Run a hose on the windshield, remove the cover for the fuse box, remove the glove box and have a look while the hose is going. You might have to get someone to help you.

The AC drain hose goes through the floor fowand into the engine compartment and into the frame. Then when you use the AC water will drip from this drain hose to the center of the vehicle.
