I have a 2000 S430 and yesterday it started having the hazards come on intermittently. They would only blink once or maybe twice and then go off. At the same time the interior dome lights would come on and then 30 or 40 seconds later the lights would go out, just like if you had opened and closed the door. Then when I pulled into the garage and shut the car off, when I pulled the key out the front two windows and the sunroof opened about one inch, totally on their own. Sounds like there is a short somewhere. Has anyone had something similar to this or know what this could be? Thanks for your help.
