Hi all,
I spent a long time last night with my son pointing the hose through every spot that I could think of and no water came inside.

Frustrating.

I am wondering if it would be possible for condensate from the heater core/evap box to drip down. The only thing about that is that it would collect in the passenger side and the problem I have is the driver side.

I'm a little reluctant to patch up the floor until I figure out how the water gets in there (because otherwise I will be doing this again very soon.

Here is an idiot question: Can I drill a few small holes along the floor pan for drainage of the driver side floor pan?

What I would do is first check with your local inspection folks that it's ok to have a drain plug. The wranglers have had drain plugs in the floor for years, so I would think it's ok.
Then go to the hardware store or look online for a plug (or two) and then you know how big a hole to drill.

Are you sure it's leaking water from outside? The driver's side can have moisture problems from foot traffic. Here in MA when it snows it's inevitable that snow from ones feet gets in the car, it melts and you have moisture that sits in the vehicle.

Anyway, if it were me , I'd definitely go the plug route.

You could try taking it to a car wash... just make sure you don't choose the undercarriage option.

I would do the repair and then leave the carpet out for awhile until you discover where the leak is. Do a couple searches on the net, there is a lot of info about water leaks. On the driver side I have read about windshield leaks and about water dripping on the plug in the firewall and coming into the cabin that way. Try a hose on that plug from the engine bay and see how it goes. Also, try water in the door hinge area. I wouldn't have an open drain under the carpet. Water would most likely find its way in rather than out. Also, need to try to check for leaks around the entire Jeep. My driveway points down and I found that water was leaking around the hatch seal and working its way forward.

There are quite a few holes in the original and the new floorpans. There are 2 3/4" holes with rubber plugs, then a couple of smaller ones, plus a very large one with a metal plug that clips in. I ended up welding the large hole and use the 2 3/4" ones for drains.

As Suprmn said, leave everything out after you fix the floors until you find where it's coming in.

If the floor had a rot hole for a while, then moisture could be coming from underneath (rain/snow). That padding wicks moisture and takes forever to dry out. I have to do the same thing on mine come spring. My DS carpet and pad is soaked. I had the carpet out this past fall when I did rust repair and I must have missed finding the leak.

As someone else said fix the holes and leave the carpet out. Drive it and see if it stays dry.
