Front driver's side headlight and turn signal quit working

If both the lamp and signal stopped working at the same time - and you've tried replacing bulbs with no success - then you'll have to do some testing to find out if there is power at the respective light sockets. If not, you'll need to trace the wiring back to where power is lost. This is not a common issue; I'd also check for the presence of aftermarket lighting components perhaps. www.repairpal.com/repair-shops
