Do you have working headlights and running lights?

Do the reverse lights work? Do the brake lights work? The turn signal and reverse lights are on the same fuse, if the reverse lights work then the fuse isn’t the problem.

Does the 4way emergency flashers? Try pushing/pulling the 4way flasher a few times, sometimes the contacts in the turn signal switch get gummed up.

Check for power on the purple wire at the turn signal switch connector with the ignition on. If you have power at the purple wire, chances are the turn signal switch is bad.

Headlights,running lights and brake lights work

Did you try playing with the hazard switch? Did you check power on the purple wire (with the ignition on) at the turn signal switch? If the hazard switch does nothing, and you have taillights and brakes lights, and power on the purple wire, then most likely the turn signal switch itself is bad.

If you have reverse light, and no power on the purple wire, check/replace the flasher.

Probe for power at the signal sockets with the bulbs out, key on with signal on to L+R. Check grounds and bulbs themselves.
