    I am getting a running/sloshing water sound from inside the dashboard whenever my AC is on. Anyone have any idea? This only happens when its set for low-temperature, if i set it on heat the noise isn’t there.

    What would happen if you were to run a coat hanger gently from underneath the car through the air conditioning water drain hose It's evaporative drain I guess or when your air conditioning is running at a full tilt and pretty much stabilized do you see water on the ground wherever the car's been standing with the air conditioner running? And it shouldn't be just a couple tiny drops if you've been sitting there 5 minutes you should have a pint or so on the ground or half a can or something like Coke can. Sounds to me like water's not getting out of that tube at a good enough rate and some is sitting in your evap case and that is bad.
