Where is the flasher located

If they just stopped all of a sudden you should check the flasher usually located in a fuse box

Simple method without mystery:

1. Turn blinker flashers on;
2. Listen for clicking;
3. Find source of clicking. It is the flasher. :)

NOTE: Emergency flashers and blinkers usually use a separate flasher unit, but one is close to the other. If your blinkers do not work but your emergency flashers do, find the emergency flasher unit by finding the source of clicking, then locate the blinker flasher nearby. They will ALWAYS be underneath the dashboard on the driver side.

Follow the flasher wiring to fuse box and locate the fusible link. Looks just like the wire but softer exterior and it's a fuse able wire that can break down. Should be along the driver fender under hood.

Try replacing the turn signal flasher first.It should be above the drivers feet near the steering column and looks like a typical flasher unit. A little round canister with 2 wires,sometimes 3 wires.It is what you hear clicking when using the turn signals.

The Lincoln Continental flasher is integrated into the "Multifunction light control module" part # 13c788. Cost junk yard around $50. There is no stand alone flasher relay as in the older or more senseably engineered and cheaper cars.

Hope helps.

No Turn Signal Operation (blinker)The turn signal lights in your car are a basic electrical system that controls the front and rear blinker lights to alert the intended direction of the vehicle. We have listed some of the most common problems and repair troubleshooting tips below:
Troubleshooting Procedure
To start troubleshooting this problem:

• Turn the key to the on position (do not start engine)
  
• Inspect the system fuse located in the fuse panel and replace if needed. If you cannot find the location of the blinker fuse consult your owner's manual or an online repair manual
  
• When a blinker flasher fails it can cause blinker lights to say on, not blink, or not go on at all. To test the blinker system flasher, remove the flasher unit and insert a jumper wire between the two terminals. If blinker stays on in both directions without blinking, replace the flasher. If you cannot find the location of the blinker flasher consult your owners manual or an online repair manual.

There is 2 different flashers. One flasher for the turn signals and one flasher for the hazards. If you turn on the turn signals and the turn indicator on the dash lights up but doesn't blink, then most likely it is the turn signal flasher that is bad. Good luck.

flasher located at bottom of fuse box its round bout the size of a pop bottle lid,hazard flasher located at top

Your F--150 has 2 flashers, emergency and turn signal. Both are mounted on the fuse block under the dash. The turn signal flasher is mounted on the front of the fuse panel, the emergency flasher is mounted on the rear of the fuse panel. so replace the turn signal flasher should solve the problem. Let me know how it goes.

Relay or Flasher unit will be located in or near the fuse box,,,your owners manual will tell you where it is,, they are easy to replace, and cheap to buy.
