Does this car have LED's or has the bulbs been replaced with LED's? If the bulbs have been replaced with aftermarket LED's this is your problem. You must have the correct bulbs to supply the correct resistance or the blinkers will cycle to quick. I would replace the bulbs at the both the front and rear even if they work. I have seen bulbs work even though the resistance is off. Please let me know.
