2007 Avalanche LT Will Not Start

Asked by Nov 02, 2015 at 06:00 PM about the 2007 Chevrolet Avalanche LT

Question type: Maintenance & Repair

I left my hazards on for 10 hours, which ran the battery down. I tried to jump it
with a Booster charger, and apparently fried something out. Now the battery is
fully charged, but no interior lights, door locks, back power windows, or
response to key when turned in ignition. All fuses and relays have been
checked, and are good.

Did you reverse polarity when jumping the car? Check the accessory hot wire and make sure the connection at the battery is good.

No, I did not cross polarity.

Not sure on yours but a good chance that because of the battery being run down that it lost its memory with the parameters to allow it to start. Some vehicles you need a power source just to change the battery. Sorry to say but I don't know how to reprogram it back. It is just an idea to check into.
