Wet Emergency brake switch

my daughter bought a 2010 acadia about 2 years ago , recently the emergency brake light and the chime comes on when she is driving even though the brake is not set .
i looked at the switch and noticed a significant ammount of moisture , i sprayed the switch with 90% IPO to dry it out and it resolved the issue for now !
i read some posts talking about clogged drain tubes or pipes that can cause this issue but my daughters car does not have a sunroof , anyone had this problem before and know how to fix it ? i did not notice the floorboard being wet

    It could be a clog in the bottom of the fresh air vents (under the wiper blades). These cavities can fill with leaves and debris and clog the drains--then you are driving around with a little fish tank up front there. Eventually the water finds its way along wires and hoses and drips into the passenger compartment.

    So someone should remove the cowl and look inside to see if this is the case.
