Humidity will condense on the exchanger & drain through a pipe onto the ground. Almost always visible after stopping for a bit. If you do not see a puddle near the firewall on the passenger side, then condensation may be accumulating in the air box. it will smell very musty. The drain pipe is usually a rubber pipe and somewhat flattened on the end.
