The turn signal isn't commanded by the ballast but the headlights are. To confirm it's a bad ballast swap them from side to side and see if the problem follows. They're screwed in to the bottom of the headlight assembly and very easy to swap. You can find ballasts aplenty on eBay. https://www.ebay.com/sch/i.html?_fro...sedan&_sacat=0

First verify it doesn't turn on when you turn the hazard lights on, if it DOES work then there's something wrong inside the BCM. If it does not turn on then verify the rear turn signal works on that side (with the turn signal switch, not the hazard lights), if no front or rear turn signal then check for proper operation at the BCM, left side turn signal is pin 45, right side turn signal is pin 46.
If the rears work then it's likely a wiring issue at the headlight or something feeding it. Start at the headlight plug (pin 6) and test for voltage, if you have voltage then there's something wrong internal to the headlight assembly, perhaps the socket is corroded or a bent pin in the harness. If there is not voltage at pin 6 then trace the wiring back or just abandon that circuit and run a new one back to the correct BCM pin.
Here's the harness at the light.
Here's the harness at the BCM (Section M2 has the pins you want).
