Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Holy macaroni! This is a heck of an electrical issue! Since you've checked most common grounding points and still have issues, consider the possibility of a damaged or corroded ground wire within the wiring harness. Look for any signs of wear or damage along the wiring harness, especially in areas prone to rubbing or exposure to the elements. Using a wiring diagram, trace the ground circuit for the affected systems to pinpoint the issue. The fact that the battery is going dead indicates a draw on the electrical system. Even though you have ground doesn't mean something isn't staying on after you shut the truck off. If you have any other questions feel free to call us at 877-913-1554!
