lots of water on the floor after using a/c

On the carpet of the vehicle, or on the ground under it? If on the ground, that's normal. It condensates and drips. If on your car's carpet, that means there is a A/C leak and it is leaking refrigerant in the cab.

It's on the floor, under the carpet. If refrigerant is leaking, a/c wouldn't work but it works fine. It appears condensed water.

You drain is stopped up. I will try and find a location for it for you.

http://www.toyotanation.com/forum/122-2nd-generation-2008- 2013/417820-ac-evaporator-drain-location.html -- check this out. Its behind the front passenger wheel drive shaft, a foot or 2 back.

Delete the space between(2008- 20) should be (2008-20) for address to work properly.

Thanks; will check it out. Would the water cause any problem? Like shock or electrical problems?

No but carpet will start to smell like a wet pair of old socks.

Judge is a jeep grand cherokee set up the same as a toyota highlander?

Where is the drain on my 2012 toyota highlander

I have 2008 Highlander Hybrid. Water was leaking on the front passenger's carpet and under the second-row seats as well. I found 3 missing grommet plugs under the rear bumper cover. I replaced those plugs and never had wet carpet again. You can see more pictures here: http://www.diy-time.com/automotive/toyota/fix-water-leak-inside-cabin-2008- highlander/

yes, i have the same problem, the same holes

Seriously, why do people who obviously know nothing about cars answer these questions? Water is not a refrigerant. If you have not a clue, dont answer. Answer By Adam: "If on your car's carpet, that means there is a A/C leak and it is leaking refrigerant in the cab."
