This 2014 Chevrolet Captiva came in with the complaint that the battery would go dead if the vehicle sat for more than three to five days straight. The vehicle had a distinct musty odor and water was found on the floor at the rear of the vehicle. Knowing this moved my search for the cause of the battery drain to a module mounted on the floorboard. After narrowing the drain down to the Logistic Mode fuse in the interior fuse box, I used the wiring diagrams to identify the modules on that circuit.
