Please clarify for me if both turn signals work correctly when the 4 ways are turned on or do they work together. If they work together than you need a new turn signal flasher. There are two, one for the for ways and another for the turn.

Hi! check first for any blown fuse.
INSPECTION
1.
Check for a burnt fusible link with an ohmmeter.
2.
If a fusible link burns out, there is a short or some other problem in the circuit. Carefully determine the cause and correct it before replacing the fusible link.
The fusible link will burn out within 15 seconds if a higher than specified current flows through the circuit.

To fix this will require a new turn signal switch, this seems to be a common problem with these multifunction switches.

HI. the flasher is faulty or damaged. replacing this device will fix your issue.

There are separate fuses for the turn signals and blinkers, but you should check both of them just to see if they're good.
You may have a burnt out turn signal bulb as well. I know that this sounds like an obvious answer, but a single bulb can sometimes disable the entire system because of the way that some flashers operate.
You could also have a defective turn signal/hazard light flasher. This is located under the dash board on the driver's side between the steering column and the door. You have to remove the sound insulation/kick panel (the cover on the bottom of the dash board) to reach the flasher (it is easy to remove - I don't think you even need tools).
SOURCE: My blinkers wont work but the hazards work. No fuses burnt out.
That would most likely be the switch itself. Fairly common

Two different circuits. Do all four lamps blink when you turn on the hazards? Does anything light up when you use the signals (dash indicator, front but not rear)?
