The turn signal flasher on a 2006 Ford Explorer is under the dash on the driver's side. This vehicle has two flasher units, one for the turn signals and one for the hazard lights. They are next to each other.
Most likely turn signal flasher
The flasher relay and turn signal relay are located under the instrument panel near the steering column.

According to my Haynes repair manual , the turn signal and hazard flasher relays are located under the instrument panel to the right of the steering column. (Helpfull)

The turn signal and hazard flasher relays are under the dash to the right of the steering wheel according to my Haynes repair manual On my 1999 Ford Explorer, the turn signal and emergency flasher relay is to the left of the steering column behind the electronic monitor adapter. Factory flasher is yellow and clipped to a metal flange. My after market flasher is black and has one less posts but works perfectly. It does not have the clip on it so either leave it hanging or zip tie it to the flange.

Impossible to answer because you fail to list make, model, and year of the vehicle.
It's incorporated in the turn signal stalk.
