2000 Dodge Dakota my turn signal will freeze while flashing

i have a 2000 dodge dakota and randomly when using my turn signals the light will stay on without flashing, i have read that this may be the "turn signal flasher" and i have tried to locate one online but cannot seem to do so, it would be great if someone can let me know if this is the problem, where i can get the part, and where the singnal flasher would be located on the truck
