After the car runs 2 minutes there is a gurgling/bong rip sound behind the dash on passenger side. I can't see the water dripping or running, but it's very damp on the pass floor mat. After a few minutes of gurgling, the sound goes away completely. Any help or input much appreciated. I just got the car used and found this problem. Thanks.
