Cadillac Repair: 2004 Cadillac CTS, drain location, cadillac cts

Question
My car has started a fairly constant flow of water into my passenger side floorboard. There is usually standing water in the floor by the time I arrive at my destination. I can also hear water inside the "works" of the car. I am by far not an auto expert (I can roll down the windows and put gas in the tank!!). I don't want to go to a repair shop and have unnecessarily expensive work quoted to me. Can somebody help me out so I have an idea of what to expect and look for??? THANKS!!

Answer
If you are POSITIVE that the fluid is WATER and NOT anti-freeze, This would be caused by a blocked drain tube in the evaporator housing and all you need to do is clean out the drain.

If you need pictures showing the drain location, E-mail: onlineautohelp@msn.com
