I have a 95 325IS everything is pristine on it, everything was working fine, 3 days ago this started. Put on the left turn signal it works properly, turn on the right turn signal and all the signal lights flash as though the hazzard light switch was turned on, I noticed this because both turn arrows on the dash started flashing at the same time when signaling a right turn

,
Any direction to start troubleshooting would be a great help. All lamps are lighting so it is not a bad lamp. Possibly a bad flasher relay?
