Why Does the Car Air Conditioner Make a Gurgling Water Sound?

[LaJesse]

The reasons why you can hear water sounds when the car air conditioner is on include insufficient engine coolant and detached central air conditioning hoses. The specific causes and solutions are as follows: Insufficient Engine Coolant: When you hear water sounds with the car air conditioner on, this sound is produced as water passes through the heater core. Check if the engine coolant is insufficient. The solution is to first add antifreeze and then press the accelerator to release air. Detached Central Air Conditioning Hose: When you hear water sounds with the car air conditioner on, it is because the air conditioning condensate water is supposed to flow out of the cabin through the hose. Check if the central air conditioning hose is detached. The solution is to reinstall it.
