I've got a 2002 Camry and for the past couple of months have a weird sound coming from the driver side of my dash. It sounds like liquid sloshing around in there. I just haven't had time to take it in for repair and was just looking for anyone who may have any idea what this could be. It's very noticeable when the car is cold and when you accelerate you can hear it sloshing.... any ideas out there?
