Usual suspects?
Water sits in puddle on front passenger floor, little bit in the back near spare, little bit of rust blister forming right above fuel door from the inside
I want to trouble-shoot this before I install my new/used carpeting and interior.
I want to take a garden hose and start snooping with it, is there a better way?
I couldn't bring up joe's link but:
UN-Usual suspects, but still suspects:
1. I chased a leak for a year, I used the hose diagnostic. I had ripped off the rain gutter trim on an errant tree limb so I found that the gutter that usually channels water away from the "wing" window, was channeling water (alot of water) straight flat across the window. It leaked, alot, but just in a 1/16" stream (especially if I parked with the front end downhill). Every time it rained I had a small lake on my P side. In the process I sealed up everything, heater box, wiper cowl, windshield. Still leaked. I saw the little stream on just the right day, the right angle, the same way I parked it every night. I reinstalled the guttter trim, NO more leak...
until
2. I found a bunch of water all along the side of the Jeep BEHIND the drivers seat, under the back seat, and into the cargo area. I read on here that the roof rack mounting screws could leak and the water could flow down the pillars into the Jeep. I unscrewed each screw and filled the hole with black RTV and replaced each screw. It has not leaked for 2 winters,
at all.

My suggestion is, since you are replacing the carpet, to get it all out (the carpet) and have someone douse your ride with a hose, spend some time during the deluge with a good flashlight (CSI style) to see if you can isolate where the water's getting in.
