What causes a lot of water in your passenger side floorboard??

Hello, when the air conditioning system runs, it removes moisture from the interior of the vehicle in an effort to cool. That moisture builds up and must drain from the evaporator box. There is a tube that drains then water through the floor of the vehicle. If this drain is clogged or the tube is not in the right place, water can overflow or leak onto the passenger floor area. Check the drain tube to ensure it's free of restriction and routed properly. Keep in mind - this is the most likely cause, but not necessarily for sure the cause. www.repairpal.com/repair-shops
