I have been having a problem with the flashers on my 1998 328i. Sometimes (not every time) I start the car the flashers will start and not turn off. I have tried restarting the car (they even stay on when the car is off), locking and unlocking the doors. When I hit the on/off button for the flashers they just blink twice as fast, likewise when I use the turn signal. Sometimes they will stutter and them come back on. Eventually after driving a few embarassing miles they shut off. Any help with this problem will be greatly appreciated.
