Hello, I have a problem with the water sound when I turn on the AC for 20 or 30 minutes I start hearing water sound from the right side of the passenger side, sometimes I hear it behind that glove box I am not really sure where it is from however, when I shut down the AC the sound goes quiet immediately,
I went to the car shop and the Mechanic told me that the water drain is working just fine and the car actually drains the water outside
Also, the level of the coolant water is the same above the maximum mark
Can somebody help me figure out where does the sound come from?
