Issue started a while back. Radio would go off and on, keyless entry wouldn't work. Replaced radio and is was fixed, for about a week. Then noticed the underhood light was loose. Replaced entire fixture, worked a couple of days now nothing again. I have checked the fuse, it's fine and have power to it. I've checked and rechecked grounds. Don't see any indication of bad wires. Read a post about the actuator self diagnostic test, tried that but can't get the test to run. All gauges work so I don't think it would be cluster. Any ideas?
