At no particular time, the emergency flasher lights go on. It can be while I'm driving, or while the car is parked. If while it's parked at night, the battery is dead in the morning. Another strange thing is that when it happens, it sounds like the auto door locking mechanism is kicking in and sometimes my overhead lights come on.

We've already replaced the flasher switch and it still does it. Sometimes it will turn on and when I hit the switch to turn it off, it will come back on within seconds over and over again, maybe ten or 20 times in a row.

Does anyone have any idea what's going on?
