Car runs really well and if I start it once an hour no problems, but if it sits 2 hours the battery is discharged enough to not start, run the radio, no power locks, completely dead. where should I start looking??
Thanks

The best way to troubleshoot a parasitic drain is to connect an Ammeter to the battery and see how much current is being pulled with everything off. Once all modules go to sleep, a current of around 150 - 250mA should be normal. If you have more than that, you need to pull each fuse one at a time till you find the circuit that is causing the drain. Check on YouTube for videos on this subject.
