Turn signal flasher
Try in or near the fuse box
A TNS relay is located in the fuse box of a vehicle. It controls the vehicle's turn signal lights, running lights, taillights, and dash lights.

There isn't an external relay. The FCM (front control module on the fuse box under the hood) controls the lights through internal circuitry.
The turn signal relay and the flasher relay are the exact same thing. The relay switch controls the turn signals.
The head light relay should be marked in the relay centre.
Check the signal light fuse, the signal light relay, and the signal light switcher.
Replace the turn signal flasher relay.
Depending on what type of vehicle it is, it could be the combination flasher relay. 2000 Dodge Caravan, same problem. Replaced DRL/Flasher Relay, problem fixed. Was an expensive dealer only relay...
Try checking the tail light relay.
The flashers are in the DS fuse panel, behind that fuse panel there is also a flasher relay that controls the truck and trailer signal lights and the trailer brake lights. To get to the back of the fuse panel you must take the bottom part of the dash off.

The turn signal flasher relay on a 2005 Ford F250 is located under the dash near the brake pedal. It controls the pulsation of the turn signals.
