If it's rainwater, then the drain hose on the bottom of the air box is clogged. You can blow it out from up top sometimes, or get underneath and rod it out with a stiff wire. Easy fix. However - if it's coolant leaking, you have a bad heater core. This is not an easy replacement on the Bonneville, a lot of the dash board and console has to come out.
