no such thing as a vent hose. what is the issue you are having

I probably should have said drain hose that the moisture comes out of from the a/c
thats better. bottom of the ac/heater case. around the center or passenger side of the car. can acess from under the car. carefully clean out the debris clogging it till the water drains out.
