I made this video to help anyone who is having water leak into their car. I found the problem. It may not be just the windshield leaking water. It could be your seal. Between the seal and the A pillar is a gap that can leak water right in under the dashboard. Which in turn leaks right on the fuse box and gem module. I hope this helps anyone who is having the same issues I've been having.
