Your A/C drain hose may be plugged. If so, the condensate from the A/C box will leak onto the floor, and eventually soak the rear carpet as well. This is a common issue. It is under the glove box, close to the passenger floor. Remove it and make sure that it is open. Alos, always run the A/C in the RECIRC mode.

Water in the trunk can be from a bad trunk seal or poorly sealed taillamp seams

You may have a buildup of A/C condensate water in the A/C cooler box. Start the car up, and run the A/C; you should start to see water dripping out from under the car onto the street. If not, the A/C condensate tube may be blocked or dislodged from the A/C box. The water then leaks out of the box onto your floor. The drain is on the pass side, under the dash, close to the center console. The pipe goes thru the body. This is a very common issue.

Hi, we also have a 2002 Toyota Rav4 and developed a leak in the front driver's side of the car. After much research, we discovered that the drain wells from our sun/moon roof were clogged. If you have one of these, I suggest that you open the sun roof and look carefully. You will notice some tiny little holes in front and in the rear of the sun/moon roof tracks. Over time, these become clogged with dust and debris. You need to find a long, sturdy piece of thin wire and run it down the holes. To test if you have properly unclogged these, take a small amount of water and pour it down the holes. You should see water coming out of the drain wells under the car around the rear of the front tires. Hope this helps.

I think that I can help you. It sounds like your drain-tube is plugged up. Get in the passenger side, and pull the carpet back from under the glove box. Look for a black rubber pipe that goes from a black box, and pokes thru the firewall, on the passenger side. Remove the hose from the box, and have a container ready to catch water. If water comes out of the black box, your drain hose is plugged up. Clean out the clog, and you will be golden.
