Hello
I am hearing sloshing / Fluid moving sounds from behind the dash area, around the the AC when I brake, or start the car. When driving, with A/C on or off - Everything works, but it is a noticeable sound of fluid sloshing around.
Is this normal, do I have a problem, or does anybody have a similar issue.
Thanks!

prob have air in the heater core through the cooling system. needs to be bled. also, the blend door actuators tend to go bad on IS's making a sort of mechanical "fluid" sound at times when they get stuck and try to operate. hope that helps.

You hit it right on the head, this is common in regions that experience a change in seasons as the variance in temperature tends to promote air in the system.
