Hi !
This wet condition may be caused because the evaporator drain pipe is short and the water wicks its way into the vehicle around the drain pipe. The water is the result of normal condensation caused by high humidity, high ambient temperature, low blower speed and long periods of driving (See photo)
Try to clean out any dirt or "crud" that might be built up inside the drain tube. This can be done by blowing compressed air in short bursts into the drain tube, or use a long coffee "stir stick" to gently push into the tube. If there is any blockage, the extra water will start to drain out when the drain is clear.

Serge is right........what you can do is put the the ac mode switch in the vent position, blower on high, and close all the registers in the dash.....this will cause the ductwork to build up a back pressure.......then carefully reach through the wheel well or from under the car(jack it up), and see if you feel air coming out of the elbow....if no, it's plugged......

Another place water could come in is from the fresh air intake from under the cowl on the passenger side....

If neither, could be a seam problem.....
