Any electrical system on the vehicle can cause a battery to drain completely if there is a short. To trace the short, remove all fuses from the interior fuse panel, and see if the battery drains. Install the fuses one by one until you locate which fuse causes the battery to drain. With the system isolated, you can now troubleshoot the short. Additionally.. You can also first by checking all the lights of the car. Glove box light, under hood light, trunk light, interior lights. Every light basicly. A light is the easiest to find, and to fix if its the problem. Good luck
Dead cell in battery, a light is on somewhere on the vehicle, or a relay is stuck.
