I parked on the side of the road today and as I walked away from the car I could hear a hissing sound coming from the car. Upon looking under the car from the passenger side, I could see droplets of water dripping from under the car onto the exhaust midsection. This was in the middle of the undercarriage about where the two passenger doors meet. Any idea where this water might be coming from? I though maybe aircon however I assumed that would be further up near the engine.
