Oldsmobile Forum - Oldsmobile Enthusiasts Forums - 2001 Aurora Water Leak Problem

My 2001 Oldsmobile Aurora (4.0 LTR) has a water leak in the trunk and somehow under the drivers seat by the arm rest. The water pools in the trunk in the spare tire well. Recently I've also gotten a water problem on the right side under my driver's seat.

The sunroof is closed but I need to get that fixed as the motor is bad. I've also read somewhere that water leaks through the trunk into the backseat and shorts out wiring. The trunk leak may either be through the area surrounding the license plate OR I have a bad seal around the trunk area. Can water leak through the trunk and run under the driver's seat?

Does ANYONE know how to trouble shoot these issues OR a fix for either? I also need to get my sunroof fixed which I believe may be the issue with some of the driver's seat water leakage.

Thanks!
