The cilenanode over heets and won't turn the motor on because the battery won't

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sounds like your DeVille's solenoid is being a real power hog. When the starter solenoid draws too much current, it can overheat and drain the battery, leaving you stranded. You might need to replace the starter assembly if the battery checks out. As a note, sometimes a faulty ignition switch can also cause similar symptoms. To get this sorted out, you might want to visit your trusted mechanic. If you need more advice, have other questions, or need to find a certified repair shop in your area, just let me know!
