Whenever the car is rained upon, water runs into the fan motor air intake, then into the fan blower motor, which is inside the car behind the glove box, and then runs out onto the right front passenger floorboard. I have had to replace one blower motor that shorted out from the water in it, and have to pull the carpet up so it can dry out. Also, afraid of the possibility of mold growing either in the air vents or in the carpet. I took the car to the dealership and the service representative told me he has seen other cars like mine having the same problem. The dealership sells a part to install under the hood over the air blower intake to channel water away to correct the problem.
