my directional signals have stopped working

check the fuse panel directly under the dash by the steering wheel. There should be a diagram in your owners manual that shows which blade fuse to check an or remove an replace. If not go to your local Autozone or Ford dealer an have them use a volt meter on the fuze panel to see which isn't working. Or do yourself if have the tool ( usually around $45 for a good dependable one at your local tool store )
