Help c6 no start
Question about my c6 base, my car did not open when i was near with my fob so i had to make my way in thru my trunk. New batteries in fob. Then i proceed to try and start my car and the clicking sound then my dash lights up and press my start button all the dash lights go dead. But i put the window wiper switch on high the car will start without my foot off the brake. So then i turn my window wiper switch off all my service lights come on and my scanner says i lost all communication with al my ecm and bcm. Any help suggestions?

Your car does not know anything about your fob being near until you either try to open the car door, try to open the rear hatch, or press a button on the fob.
Can't help you with the other activities.

Very likely a car battery on its way out. Today's computer-controlled cars do wacky things when battery voltage gets low, and Corvettes seem to be particularly sensitive to low battery voltage. First thing I would do is fully charge the battery and have it load tested to verify it is still good.
I recently had my battery (at least 5 years old as it was in the car when I bought it) fail to start the car, then cause all sorts of wacky symptoms - dash lit up like a Christmas tree, exterior lights on when hooked up to the charger (including only the passenger side headlight). I fully charged the battery and the car now starts fine. I threw a set of jumper cables into the trunk as insurance, in case the battery is really bad and won't hold a charge. I don't want to replace the battery now, when I will only be driving the car occasionally for the next 4 months, unless the battery is truly bad. I will replace it next Spring unless I find out when I occasionally drive the car that the battery is bad.

Could this be a ground issue, have you checked that body ground point that is almost underneath the battery? I just pulled this on mine - cleaned with emery cloth and applied light electrical grease to stop corrosion.
Edit: was battery replaced before or after this issue? If before then clean the terminals and connectors.
