I've seen a lot of threads about water on the passenger side and a lot of great suggestions about how to fix it. I, however, have a lot of water on the driver side floor board. I parked it inside last night and used my shop vac to suck up the water and then checked on it in the morning and there was more water. Any ideas???? I'm at a loss.

 

The problem is that the carpet acts like a sponge. You suck up the water and it collects again. When I did the AC wet carpet repair, I did the same thing; suck up the water. It came back. I had to lift the carpet and let it air dry. Look at the water and smell it. Make sure it is not coolant.

For your specific problem, you may have a door seal leak, windshield, or plugged cowl drains. You can put some soapy water on the test area and blow air from the inside to see if you see any air bubbles. Or run water on the outside and check for leaks.

 

same issue for me? I looked in the cowl on my 99XJ and did not find the drain holes, where should I be looking in the cowl area? thanks...sorry to jump in but its an older thread :-) thanks
