Water is leaking into the footwells of my car - what's causing it?

My Jeep Cherokee has started filling up with water in the driver's side footwell - the front and especially the rear but only when it rains. A mechanic has done hose test and can't find anything. He says he needs to strip out the seats andcarpets to look further. Do you have you any ideas?

It is most likely a blocked bulkhead vent well drains that leave rainwater nowhere to go except via the pollen filter into the cabin of the car. Pop the bonnet and have a look under the grille at the base of the windscreen. The drains are either side.
