just noticed the date, oops. the same advice goes for any car though

Is there any aftermarket equip on it? Look there first. Then look into doing a voltage drop test on the car, systematically removing the fuses until the suspect system is found. From there look for an obvious malfunction in a component. Every car line I have worked on has this issue at some point, BMWs are hell with it, Mercedes are better, all have it. hit me back if ya need anymore advice.
