Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.Google+

ac condensation filled the front foot well.
Water is leaking into the footwells,and a gurgling noise is coming from inside of the car .Sprinkles of water comes from a/c vents, when a/c is turned on. Also Battery light is coming on and the battery and alternator have been tested ,and they are both good.Moisture is believed to have gotten into the dash.The indicator,which lets you know how much gas is left,and when the car is put in drive,blinked out for about a month.All of a sudden ,it came back on,and that was when the battery light appeared.
