I have an 06 SS
I am getting water on the driver side leaking from under the dash at the door hinge area.
First I cleaned out any debris under the hood around the hinge area and through out the engine bay. lots of trees here and spring is tough to keep it cleaned out.
I pulled the side panel on the dash out (the area not seen when door is closed) and the bottom panel under the steering wheel. Dried it all out and wrapped several areas in question with strips of cloth to isolate possible leak points.
Water is coming from the base of the pillar it would appear, opened the sun roof and found track filled with water. where is the drain ?

Any help would be appreciated, Hot Rod Frank
