Battery drains overnight

Hello,

You could have excessive parasitic draw (current drain) on the battery.
Every electrical circuit will have a certain amount of parasitic draw; however, it can become excessive due to any number of faulty electrical components. Like a glove box light staying on or a shorted-out window switch etc.

This vehicle should not have any more than 35 milliamp of parasitic draw.

In order to find out what is causing the drain you will have to use a multimeter and check the current drain on the battery, as you remove different fuses.

Here is a helpful video that shows exactly what to do:

I have attached the test procedure below as well.

Please let me know if you have any questions.
Thank you.
