2003 Mitsubishi Outlander water leaking

Air Conditioning problem
2003 Mitsubishi Outlander Two Wheel Drive Automatic

There is water leaking into my car on the passenger side near the feet. My hubsand asked the mechanic and he said that because the water is cold, no smell, that the is probably condensation from the air conditioning. He said there is a rubber tube that may just be backed up and that's it's really easy to unclog, just crawl under the car etc. Anyways they tried but couldn't find the tube. Can someone help how to locate it on a Mitsubishi Outlander?

Thank a million!
