GRAndcherakee 1993 A/C drainage

Hello, I need to know where I can clean the drainage of the air conditioner of the Grandcherakee Jardo 1993, the system works as a freezer but the carpet of the floor gets wet when I turn it on, I know it is the drainage because there is no classic dripping out but I need to know how to uncover without causing other damage, I will be very grateful to whoever helps me to solve this matter.
Cordial greetings for everyone from Ecuador

Demonar all the torpedo of the vehicle but eye may be that it is broken the radiator also or some hose on the way lucky.

Hi Kikemec, thanks for your answer but I do not understand that it is "torpedo", I also do not understand what the radiator has to do here, in addition the heating system is disconnected, you may be that you were wrong the answer, again thanks for your altruistic interest of helping.

Hi Salinero that's facilitating and for the air drain there is a hose there you throw air with a compressor and solve your problem

Thank you fried, I know that is the solution but I have been in hours under the car looking for the hose that normally exists for drainage but it cannot be observed, it seems that these cars drain into the chassis, I have consulted on the Internet and it seems that it is Jeep's problem that there is no visible hose. When lifting the carpet on the right side you can see a plastic piece that indicates that it is the drainage and coincidentally my question is "how to open that element without dancing" I aggravate you for your interest, a hug
