When the machine is parked or operated on a downward slope, water can collect around the 126-8472 Seal that is between the cab roof and the Heating Ventilation and Air Conditioning (HVAC) Unit.
If there is any gap in the sealing surface between the HVAC and the cab roof, the water can be sucked down into the gaps when the HVAC is turned ON.
