To be certain:
* Consult your owner's manual: This is the best source of information for the exact location in your specific vehicle.
* Use a repair manual: A Haynes or Chilton manual for your year and model Sebring will have detailed diagrams showing the location of all components, including the flasher relay.
* Search online forums: Search for "2008 Chrysler Sebring flasher relay location" on forums like Chrysler specific forums or general car repair forums. Someone may have already posted pictures or videos showing how to access it.
Keep in mind that some newer vehicles don't have a separate flasher unit; the turn signal function might be integrated into a larger control module. You should expect it to be a small relay-type component.
