2008 Chevy Cobalt No start, no accessory lights and no windshield wipers

Asked by Feb 18, 2014 at 10:35 AM about the 2008 Chevrolet Cobalt

Question type: Maintenance & Repair

My 2008 Chevy cobalt will not start, or even turn over.  When i turn the key to start it can hear the relay click at the body control module.  No accessory lights in the dash work, besides the odometer and the security lock comes on for a few seconds and goes off.  The windshield wipers do not work with the key on.  The headlights and turn signals do work.  It has no power to the ip ignition fuse at the inside bcm/fuse box.  
I bought the car as it is, the lady said she hit a puddle of water and all the lights in the dash went out.  She said after she got to where she was going and parked it, it didn't start back.  Any help would be greatly appreciated.

I have disconnected and cleaned a few of the grounds. I have not been able to get under it yet to check for loose wires. It has been taken to the dealership and they could not figure it out either

If the problem arose as a result of hitting a big puddle it's unlikely its a loose wire or bad ground. Something got wet and shorted out to cause that sort of failure. If the dealership can't figure it out, which seems very odd to me you may need to try swapping out a few parts to see what happens. I would start with the main computer. Find a friendly auto wrecker who might let you try one, or just bite the bullet and buy a used one and plug it in. Just a thought, remember, I'm not a mechanic. There are also shops that specialize in auto electrical repairs. Find a reputable electrical specialist and let him have a try.
