The car air conditioner leaked to the co-pilot?

First observe whether the engine is short of coolant, because the heater water tank will also leak due to corrosion. If there is no shortage of coolant, it can be determined that it is not a leak in the heating box. At this time, it is determined that the water appears after the air conditioner is turned on, and it can be concluded that the evaporation box of the air conditioner has encountered condensed water in the hot air.
