Sometimes my cars auxillary power will come on without me putting the key into the ignition,especially when the inside of the car gets hot from a sunny day. The lights on my dash light up and this also causes my anti-theft to go off and the power drains my battery. Also when I turn the car off after driving the A/C continues running until I turn it to the OFF position. I've had it numerous times where it has drained my battery. Does anyone have any ideas or tips that I can do to fix this problem?
do you have an aftermarket remote starter or alarm on the vehicle? that could be the problem, or it could be something wrong with your ignition
proberly who ever put in ur alarm @!#$ it most likely or somethings gettin power when its not supposed too i aint goin lie im a mechanic and if u brought that to me id proberly have a bad day,,lol...but bring it in and if they cant help u and say some bull@!#$ why they cant fix it just go somewhere else....
kinda sounds like your ecu....go through all your fuses and make sure you dont have any burnt ones....then get the ecu checked...

Check into the ignition recall with the cavaliers. That sounds pretty similiar
check the harness from factory wireing behind your deck may have melted two wires together
