PLS help, here's the scoop

So the other day it had rained and I picked up a book I needed off the passenger side carpet, it was damp, didn't think anything of it then today after it snowed yest my floor is so bad and soaked on the passenger side its not right. No leaks from seals or windows around the door that I can tell, anyone have this issue or know a fix? I'm only under my powertrain warranty now its an 05 base silver. Pls help thx! Oh forgot to say it does get garaged and was there during the snow fall, but I drove it later on wet roads

 

Did you have any aftermarket stuff done to your car? Stereo or anything? Did they drill any holes in the front firewall?

 

The car is stock besides hks exhaust and gf210's, all stock inside besides that, and I did the work myself as I'm a bmw tech, I do have access to tools and lift

 

i've had issues like this with other cars before, usually it was due to a windshield that was a replacement due to a wreck or whatever, and it was not sealed properly and would leak water onto the carpet.And also check the weather stripping on that door. Let us know what you find.

 

Turn on your A/C and let the car sit-----Is the condensation dripping on the ground after 15 minutes or so ???? If not, your drain is plugged and its backing up into the car. Ream it

 

So at lunch I brought my car into my bay and checked it, I looked underneith the dash and found water ingress on the wiring harness to a control module? Not sure what's what ina nissan yet, anyone have ideas

 

Ok hears the update! I found the cause! I'm excited cause I fixed the leak, there is a harness that goes in btween the engine bay and the passenger side floor area. In order to get through the harness goes through a 3-4 inch diameter hole right below the window drain tube under the plastic panels on the right side(passenger) of the car. The harness has a plastic piece with a rubber seal that was popped way!!! Out of place, I could see right to the floor where there was water. Popped it into place and used rtv silicone to make a better seal.

The motor was replaced about 9k miles ago and I think it was popped out because of that. Its now on record with nissan corp. So if my carpet molds its covered!

Thanks for ur inputs guys!
