This doesn't exactly fit in the audio/video section, so I'm posting it here for help. I've searched, looked at service manuals but I can't find a solution.

Long story short, last week I removed the rubber grommet on the passenger firewall to run some wires through and forgot to plug it back up properly. Yesterday I had to drive the car in heavy rain and water dripped through the firewall on the passenger side and must have shorted out the BCM. My flashers were blinking erratically, my trunk opened by itself, wipers and door locks were going crazy. I managed to get it home, pulled the battery and dried everything off. Today I drove the car again and it appeared that everything works like how it should, except for my turn signals. It doesn't blink the signal inside nor outside. My hazard button works properly and I confirmed all lights are blinking inside and out. I've checked the passenger kick panel and did not see any fried wires.

I have the PDF service manual for the Z but it doesn't have the wiring schematic. I've checked both fuse boxes near battery and driver kick panel and all fuses look intact. I was wondering if anyone can point me to the right direction. Is there a turn signal relay somewhere that I can check?
