I’m getting a sloshing noise coming from my passenger side dash/glove box area. Any ideas what it could be.TIA

Air conditioning condensation tray drain port is clogged. Pretty common problem. Depending on vehicle the usual fix is to run a wire through the port in the firewall back through the tube. Mold, mildew, dust, etc, clogs it.

I had it on a Pathfinder. Sometimes the tray will fill up and you'll get water on the passenger side floor.

 

Do you have a small drip in your driveway? Check to see if it is coming from the bottom of your door. Clogged (leaves etc) door drain holes can cause water to accumulate in the door and slosh around.
