Problem just started. After driving and shutting off ignition, car electrical is completely dead. No dome light, no dash, no remote lock, no trunk release. Jiggling ignition does nothing. First time it occurred was yesterday. Noticed that turning on driving lights disengaged cruise also. Stopped car. Placed in park. Turned off ignition. Dashboard lights flashed on repeatedly and quickly. Then all power gone. Turned key to start. Nothing. Popped hood, took off battery cover to check connection. Everything appeared fine. No corrosion ( new battery last fall. Today, shut off car, no power again. Opened door. Closed door and dome light suddenly lit and all power returned. Any ideas or more info needed?
