Why is my car making a water sloshing noise?
The most common cause is a clogged drain trapping water in the heating and cooling system. The water, formed by condensation, usually empties onto the ground. But a clogged drain can cause it to back up, leading to the sloshing sound and even dampness on the passenger-side floor.
When I accelerate my car I hear water?
Answer: Sloshing is almost always caused by air in the cooling system, which allows the coolant to drain out of the heater core inside the dashboard when the engine is off. When you start the car, the water pump sends a surge of coolant into the heater core and you hear the sloshing.

It can take multiple days of running the fan under the carpet to completely dry out the foam.
Can a bad alternator cause a burning smell?
