If the fuses are good and the flasher is new, first confirm there is power at the fuse. Next, the power goes through the fuse to the hazard switch and then to the turn signal switch. When the hazard lights are off and the key is on, you get power to the signal switch. Since there are no hazard lights either, we have one of the following problems.
Open circuit between the fuse and hazard switch
Bad hazard light switch
No ground to the hazard light switch.

If I had the vehicle, I would first confirm that power is available at the fuse. Follow the directions in this link:

If power was there and working correctly, I would next check for power at the hazard light switch. There are two power supplies. One wire is red with a white trace (from fuse 9) and the other is green (from fuse 4).

Now, if power is available, you need to confirm that there is a ground for the circuit. The ground for this component is located behind the left kick panel. (where your left foot would rest against). The ground will actually come from the flasher unit that you replaced. It will be a black wire. Check to make sure it is in good condition and nothing is loose or damaged.
__________________________
If you have power to the hazard light switch and ground, if nothing else, the hazard lights should work. If they don't, I suspect the problem is the hazard light switch. If bad, it will prevent hazard and turn signals from working.

Lets get this far and let me know what you find. I attached two wiring schematics for you to review. The first is specific to the inside of the vehicle. The second is exterior lighting.
Again, let me know what you find.
Take care,
Joe
