The commonest cause for this is a blocked drain under the cowl, and this means water overflows into the air inlet for the heater and AC.
Remove the wiper arms, unplug the wires to the WW nozzles and lift the cowl to inspect all of the drains (4).
Do it before major damage occurs, as it is coming down the hose you may have another problem but the drain inspection should be done anyway.
