Help G37 X interior leak
#2
Where near the e-brake are you talking about? Mine has a leak as well, however it seems to be coming in from the front corner of the window. A little past the tweeter it seems, and then dripping down towards the area you mentioned.

on the corners of the sunroof there are drains. These drain travel down the pillar and through the firewall. They tend to leak right at the fitting in the firewall. It can be an inexpensive diy fix if you're handy (check the diy section for details)
