Turn signal flasher location for 2001 Nissan Exterra Google Search

If the right side works it's not your flasher, Its your left side bulb, either front turn signal or rear tail light bulb.

there is only one flasher unit and it is part of the 4 way hazard flasher ununit located in the vent on the passenger side near the radio. it costs around 149 dollars. I would replace all bulb on the left side first unless the 4 way flashers work.

The flasher module is located in the fuse box that's located next to the steering wheel

Your car isn't like the old kind of flasher relays. You have a flasher module and below is a picture of its location. I hope this helps.

The turn and hazard flasher is part of the hazard switch. if there is a problem with the flasher, you will need to replace the hazard switch assembly
