locate the ac drain out in the engine compartment fire wall right side black rubber and wet and give it a squeeze. Most likely debris is keeping the evaporator case from draining A/C condensation out. Gently blow air up that hose and wait for two gallons of water to come out

Mr. Ticked Off is correct, it's an ac drainage problem. The air conditioner "conditions" air by both cooling it AND removing moisture from the air. That moisture drops into a pan and drains out the car. If the drain is clogged a little, then you can hear the water sloshing around in the drain pan. Usually you can get remove the glove box door and get to it (usually, not always, I don't know every car model). You will see something that looks like a mini car radiator (the evaporator), and a black plastic tray underneath it (the condensate tray). with a rubber hose attached (that leads to the engine compartment which is most likely the problem).

is it a sloshing or like a fluttering sound? i had a 96 blazer that would from time to time make a sloshing/ fluttering noise from the dash area. turns out it was one of the hvac doors becomming stuck between modes causing this unnerving noise. i probably could have fixed it eventually, but i traded it off b4 i had the chance. it's worth a shot.

I am a ten year vet of Chevrolet dealerships. The problem you have is common with that model blazer. You need to check the condition of the coolant in the radiator. Remove the radiator cap and look for heavy deposits, thats wat is in your heater core. Flush the system with Prestone Heavy Duty Fush, its the only one that will work. After you get the system flushed you need to find the leak that caused it, probably the intake manifild gasket.
To do this right you might want to go to your local dealer.

You have to much air in the cooling system. The noise is coming from water rushing through the heater core. A mechanic can purge the system to correct the problem. It is Ok to drive this way.
