My S70 T5 has a water leak from the outside of the car into the AC Heater box. The water pools in the fan section of the box.
The fan area is lower than the section where AC core is and the drain starts to collect from
I have checked and cleaned the drain that comes out in front of the heater core and drains out through a rubber hose though the floor
I checked and cleaned the drain and dried the fan section mid week. It rained most of Friday the car sit outside when at work. Friday arvo had water in the fan section of the box.
