I installed new carpet in my Impala this weekend. When pulling out the old carpet I noticed it was wet on the passengers side near where there right foot would be but higher up towards the engine compartment. There were no holes on the floor or in the area. So it must be dripping from above. Anyone else have this problem or an idea where it most likely may be comming from. Shall I just get a new winshield installed and hope it solves the problem? Also any suggestions on how to trouble shoot this would be helpful.
