just bought a new battery for golf put it on, and now realised that my drivers side indicaters are on and stays on no matter what you do, the only way it goes off is when i take batt off

i flick the passenger on and it flashes fine but drivers is still on but not flashing, put the hazards on and both lights are on but not flashing

. PLEASE HELP ITS SUPPOSED TO BE ON ROAD NEXT WEEK
THANKS
