Hello. I have mazda 6 2005 and rain water is coming to the drivers side from behind the dashboard. I have located the leak, it appears to be coming somewhere from above the Engine Control Module. Can't really see all the way up there because the Engine Control Module is blocking my vision. Any ideas?

 

You should remove the PCM not only to better see where the water is coming from but to check for water intrusion in the PCM. If you see signs that water has hit it then put a piece of plastic or something over it until you can fix the leak. It's pretty easy to remove. Possibilities are windshield seal/ windshield cowling seal/windshield cowling drains clogged with leaves/wire harness grommet or boot.
