* Under the dash: This is the most common location. Look behind the steering column, possibly near the fuse box or other electrical components. You might need to remove a panel or two to access it.
* In the fuse box: Less common, but the flasher relay might be integrated into the fuse box itself. This fuse box is usually located under the hood, but sometimes inside the car, depending on the model. Check your owner's manual for the location of the fuse box.
Before you start searching:
* Check your fuses first: A blown fuse is a much more common cause of turn signal failure than a bad flasher. Check the fuse box for fuses related to turn signals (consult your owner's manual).
* Test the bulbs: Make sure your turn signal bulbs aren't burnt out. This is also a frequent reason for turn signal problems.
* Owner's Manual: Your owner's manual is the best source for the exact location of the flasher unit for your specific model.
If you've checked fuses and bulbs and still have no turn signals, then systematically search the locations mentioned above. The flasher unit is usually a small, square or rectangular unit. It often has a single electrical connector.
