What could this be?

This mornin i start my car and let it run for a few mintues before taking my sis to school.Then just for the heck of it i rev a few times while waiting lol.I notice each time i rev, around 3k rpm i hear like a fluid sound.As if water is swooshing somewhere near the dashboard.What the hell is this?any help please.My 1st thought was a foul heater core.Car is an 01 gt 128k miles.

More likely it's from water that leaked down into the cabin air filter area. But I've never had water leak issues...so I'm totally talkin out my butthole.

ohhh.thats possible since also every morning theres condensation buildup all on my car from overnite coolness.aight thanks bro

It's more likely air in the coolant lines. You're coolant is probably a little low and you need to bleed the air out. Search the forum for how to do.

Is the condensation on the INSIDE of the glass? Specifically on the windshield around the defrost vents? If so, then I'd be willing to bet on leaking heater core.

If not then yes, bleed the cooling system as there is air trapped in it somewhere.

The air in coolant didnt even cross my mind.Thats prob it cuz when i swapped my thermostat months back i didnt bleed the air out properly lol.I was too impatient waiting for the coolant to flow out of the nipple.But now i see and i believe it is time for some extra coolant.thanks peeps

Like a few others said, air in the cooling system. Bleed it out, and have your rad cap checked. My 05 Jimmy was forever getting air in the system...the heater core would air lock completely and I would have no heat.....bleed the air, be fine for a few hours, then back to air-locked. Bled it once more, replaced the Rad Cap, been 2 months air-lock free.

im thinking air in the heater core like its been said, but the condensation, id bet if you pull up the carpet on the pass side, its all wet underneath and leaking when it rains through the blower motor as well.

Well im gonna bleed the coolant out the nipple valve once i add more coolant.then if the problem is still there then ill have my heater core lines checked.
