First, check to make sure that your Hazzard switch is not partially depressed and cycle it on and off a few times to make sure, if this switch sticks it will cancel the turn signal function as well.
Fuse #5 should be your turn signal fuse. The circuit consists of the fuse, the multifunction turn signal switch, and flasher. These in turn send power to the individual lamps.
Step one is to check the fuse, if the fuse is good, try wiggling the turn signal switch a bit, try to see if moving the switch slowly lights any of the lights even if its only a short flash.
Ford has had a history of these switches failing as well.
