If your hazards work, then everything beyond the switch should be good, same wiring/lamps.
There are two flashers, one each for signals and hazards, both plugged into the Convenience Center. Did you replace the signal flasher?
Signals and hazards feed from two different fuses, signals use Fuse#16 20amp. Is this fuse good? Blown fuses can appear good, measure with a meter or swap it out.
For signals, there should be 12v from the convenience center to the switch... check the BLK/ORG wire at the switch for 12v.
If there is no 12v on the BLK/ORG wire, then...
Check the Convenience Center for burnt wires, relay contacts, etc. The signal wire from the Convenience Center to the switch could also be bad.
