recently my 2016 Giulietta has started to have the glove box internally wet and has soaked the papers in there. I have taken off the wiper cowl to see if there is anything there but I cant see anywhere that would cause a leak. I am not sure when it happens either. When I removed the glove box and spray water over the windscreen and wiper area i cant see any leaks under the dash area where the glove box was. The top left and corn of the glove box insulation is wet when i removed the glove box so it is coming from that side.
I cant think of any other things to look at
