water is dripping near glove box
water dripping glove box area on 2008 Scion xB
Possibly your heater core is leaking and you would need to have your cooling system pressure tested by a shop to verify this http://repairpal.com/directory?address=11720&car_brand_names=Scion and you can check repair prices here http://repairpal.com/estimator?car_type_id=7135
There's a hose that drains from what I assume is the heater core, through the space under your glovebox (where your feet can easily kick it), and into the floor. We've been through a couple of those hoses already.
