Blinkers flashing quickly?

Yep, this happens when the electronic flasher module is going out, to be clear all the bulbs work, correct? If so, replace the flasher module here is the location. Also, I would check the bulbs on the side that are blinking quickly to make sure there are no heated/melted connections.
