Low coolant?
Heater core may have air and needs to be purged?
You may have water somewhere in the bottom of your trunk. If not, it could well be the sound of your gasoline sloshing around in the tank - older GM cars were notorious for this sloshing sound.
If the noise is coming from the dash, your condensation drain is clogged. under the vehicle, passenger side at the bottom of the a/c box is a rubber "udder" reach up and squish it to open it up and drain out the water. p.s. wear a raincoat...
Behind glove box. But you access it by removing the passenger side sound insulator. Horizontal plastic panel under passenger side console. For full access answer see blower resistor questions/answers. Behind glove box. But you access it by removing the passenger side sound insulator.

Have u checked the bearings?
The Sound I was hearing was the turn signal on reminder (sorry I have no manual)
The passenger side front tire may be rubbing on the inner fender.
Either you have a leaky heater core, if you use the A/C a lot, severe condensation buildup, but it still means the drain for the box, is plugged, under the hood. Should be on the passenger side of the firewall, under the drier for the A/C. Looks like a little 90 degree tube sticking out.
Assuming this vehicle is front wheel drive, you probably have a bad passenger side half shaft.
My guess would be components in the rear brake assembly. My 2003 Liberty kind of makes a creaking sound back there. Depending on the type of sound it might also be something with the exhaust system, which I believe runs down the passenger side.
A small rock or pebble may be stuck in tire's tread.
The sound system amp is located in the trunk on the passenger side rear.
Bend over a hook from a wire hanger, then root around up in there. Put the A/C on while you're doing it to give you some help from the top side.
