Mercury Milan air conditioner water leak causing slushing sound in cabin during turns on Mercury Milan

Some Mercury Milan owners report experiencing a sloshing sound in the cabin during turns, which may be attributed to a water leak from the air conditioning system. This sound can result from a clogged AC drain, preventing proper drainage of condensation and leading to water accumulation. Additionally, some owners find that trapped air in the cooling system, particularly in the heater core, can also cause this noise, even when coolant levels are adequate. Another potential source of the sloshing sound is a leak in the cabin air intake, often occurring after heavy rain or when driving through puddles. To address these issues, it is recommended that owners check and unclog the AC drain, inspect the cooling system for trapped air, and repair any leaks in the cabin air intake to eliminate the sloshing sound.
