My Infinity G35 2008 will not start no lights will come no wipers or Windows or anything there's nothing there after I drove through high water it was running so good and verse the light the interior lights went off then the exterior lights went off then the windshield wiper stopped working and I barely made it home and that's when everything turned off and I turn the car off it would not stop running finally it stopped running but then it wouldn't start it's set for a week I thought it would dry out but nothing I don't know if there's a certain thing that I have someone look at to take out and dry out or if anyone have any suggestions about this I'm in desperate need thank you

 

Take out the IPDM, take a few good pictures of it so you know which fuses/relays go where. Then disassemble the ENTIRE THING down to the circuit board, put it all (fuses/relays/everything) in a bag of rice to dry it out.

While it's drying out clean your cowl drains because they're probably clogged up and the water all dumps on the IPDM if it doesn't drain properly.
