Interior Rust Repair and Finding Leaks Tips
Shawn
Introduction
My GN had three quarter sized rust holes on the drivers side floor pan right below the brake and gas pedals.
Procedure
Fixing the holes was no problem (with some POR-15 and some fiberglass), but finding the cuase of the leak was a major task that took me months to do (with kids and all).
  1. Start by removing the carpet to find if there is any rust. You will have to remove all the seats and the center console.About a 20-30 minute job.
  2. The main areas of concern are the low spots in the back floor pans where the drain plugs are. In many cases the passenger side drain plug is usted out pretty bad.
  3. Now that you have the carpet out, take out the plastic kick panels on the drivers and passenger side.
  4. Remove the plastic pieces that hold the armrest and that suround the rear side windows.
  5. Remove your headliner and the plastic pieces that cover your A pillars.
  6. While sitting in the car with the windows up, have a buddy or your wife spray a hose all around your car. If you don't have a wife or buddy, the local automatic car wash will work great. (you will have to put the drivers seat back in).
  7. Use a flash light to look all around the inside of the car to see where your leaks are coming from.

My car leaked from the windshield, sunroof, both door windows, firewall (by the steering column), and lastly from some really bizzare place next to the fuse box kinda where the door hinges are.
