2007 Honda Civic partially submerged in a ditch
Two days ago I was involved in an accident on the interstate. I was traveling around 70 mph when I hit a large pocket of water and hydro-planed into a concrete barrier, blowing my driver front tire, then slide across the interstate before coming to rest in a a ditch. The water level reached the bottom of my seat cushion. It took about an hour before a tow truck was able to pull out my 2007 Honda Civic.
After the accident, I immediately exited the vehicle and left the engine running and the lights on... I know dumb mistake, I just wasn't thinking clearly at the time.
Once the car was on the tow truck, all the lights were still working. I shut them off and took the key out of the ignition. It took 2 days before I was able to recover the car and bring it home. As soon as I got it home I disconnected the battery, removed all the seats, center console, and stripped the carpet down to the metal. I checked the oil and transmission fluid and luckily didn't see any signs of water contamination, however the air intake filter was pretty damp.
My issue is I have no power what so ever. My keyless entry remote didn't work and when I stuck the key in the ignition and turned it to accessory mode, no lights came on.
Any idea what I should troubleshoot or check/change first; fuses, relays, ECU, SRS module?
The vehicle is my commuter car for work which I paid around 5 grand for about a year ago. Is it even worth fixing or should I just cut my losses and shop around for another commuter car?
Thanks in advance for any help/suggestions!!
