My Battery draining overnight when you lock it about 3 minutes go's bye and the dashboard lights comes on, I replaced the front Sam, and battery's to no avail? any idea's
If you know how to use Multmeter , you can diagnose by yourself and you will find what is draining your battery.
What I should do, I will start removing Fuses of Radio, lights, door central etc , until you will find the solution.
Battery drain can be also from bad alternator.
It could be the alarm or the audio gateway. Those are the most likely causes. But you need to test with a multimeter.
Check your alternator with a multimeter to be sure it is charging your battery.
