2014 custom, air con water drips from glove box

[Gary A]

2014 custom transit.
Air con cools cab fine, but if left on, after 30 mins water drips into cab from under the glove box, if air con is turned off, leak stops.
I’m guessing (please correct me if I’m wrong) the air con drain is blocked, had a look under the bonnet but as yet I can’t locate it.
Any one got any help/advice/photos for me on any of the above?

Long shot, but when was the last time the cab air/pollen filter was changed?

Here’s the drain hole

The A/C hoses comes loose on the back of the blowerbox, if you remove the glovebox you can squeeze your hand up and push it back on
