hazard lights flashing all the time whether switch on or off, have replaced the indicator unit and relay under the dashboard, cannot locate a new flasher switch. once ignition on, hazard lights on and cant switch off, where can I get new hazard light unit from or is it something else. Turn the indicator arm to the left and the hazards still on tho the dashboard light flashing, turn to the right and the hazards on but the dashboard light not flash!?
