My car has a water leak on the front passenger side that has now gone to the back. The water leaks from under the dash, I even hear water in the dash when I turn. People tell me I have to unclog the evap hose....Where the hell is this hose?! I cant find it!!!

 

That has to do with the heater core. There are pipes that will run to the heater core. You will have to take apart the dash in order to get to it...it is not a fun job

 

I read that this hose is under the steering column boot?!
