It could easily be from the air conditioner. Condensation can form inside the vehicle on the AC heat exchanger. There is a drain tube that runs out through the firewall.

If this is plugged, you can hear water sloshing from what sounds like behind the dash on the passenger side.

 

My passenger freedom top panel will sometimes fill with water after a heavy rain. I would check there first.

 

Hello All,

This morning I was asked my girlfriend to help me determine the cause of the sloshing sound. It wasn't until she climbed on the side step and rocked the jeep I was able to hear the sound coming from the fuel tank. I've had many vehicles and never heard a sloshing fuel tank. I thought that there were baffles in all tanks. I guess it's a 'jeep thing'.

Thanx to all who replied.

Today i drove my dads grand cherokee and there is alot of water sound, maybe this condensation thing happens somewhere where the water stays. there could be no drain but the dealer said that from the dirt the water that drips from the ac all fills up in one spot.

 

Yes the condensation could drip and get caught in the same spot and slosh around. I was just saying that there isn't a drain on the AC system. Now the heat exchanger on the inside of the vehicle might have a drain tube to let the condensation run outside, but there isn't a drain in the AD system. That's all I'm sayin.

 

This is a new one. Water sounds? I haven't heard anything on my rig......yet!

 

Oh i thought you said that its impossible for what i said to happen, but i was sure that the dealer said that about my dads jeep. sorry, good wer on the same track though.

 

Silly gas tanks!!! Glad it wasn't anything major. I hate hearing strange sounds in my Jeep.

 

i dropped several fuel tanks on cars and trucks and never saw any "baffles" in them they were all old school stuff though, where have you seen a baffle in a fuel tank. They do put that kinda stuff in aircraft
