Sloshing Noise during hard turns and fast acceleration/braking

[SirMax]

Hello world

I'm not sure if this counts as repairs, more like an observation
Whenever I make sudden movements in the car, like hitting the gas or brake semi-hard, or fast, hard steering, I hear a faint sloshing sound that sounds as if its inside the glove box, but I can't seem to find any actual water or fluid to support my observation. It's a 1996 C280, I have no idea of the service history because I recently got it but nothing seems out of the ordinary to me...
Anyone have any ideas?

Also, I'm only in high school auto shop, so my car-knowledge is very very limited, sorry :/

Thanks,
Max M

Have a look at for water below the windscreen at the bulkhead in the engine bay. Not uncommon at all for the drain to get blocked and adventually water will start coming into the cabin.

Thanks, but what is the bulkhead? also how do i clear up the drain

Open the hood. Go to the passenger side, look below the windscreen and see if there is water trapped. If so the drain hole at the bottom is blocked.
