My car makes funny noises when the AC is on

Here is what I believe you are experiencing. There is a pan that catches the water taken out of the vehicle by the A/C. It has a drain to drip to the ground and does so but when you make that left turn the water sitting in the pan it thrown to the drain side and come out filling the drain tube to capacity. The water is forced to the right because of the movement of the car. The water makes contact with the tire and is thrown. The wet tire might also pick up sand and dirt easily when wet that is thrown off the tire as well.

Sure...I query "funny car repair quotes" with google... and this is what I get!!!
