How to Replace the Flasher on a Ford F-150by Bryan Clark
The flashers, also called blinkers or turn signals, as well as the hazard lights on the Ford F-150 pickup truck are all controlled by one simple relay module. If you have a front or rear flasher that isn't working, chances are you need to replace a simple five-pin relay module located on your steering column. The part costs very little, and replacing it will take just a few minutes of your time.
Use a flat-head screwdriver to gently pry the clam-shell door open. The door is located under the instrument panel on the top of the steering column between the instrument panel and the steering wheel.
Remove the door and set it in a safe place.
Remove the blue five-pin relay from the column by pulling it gently from the plug.
Remove the screw from the top of the relay.
Replace the screw on the top of the relay.
Replace the relay with the new one (part number F65B-13350-AA). Plug the new relay in where you removed the old one.
Close the clam-shell door by lining it up and pressing down until it snaps in place.
- This process is the same regardless of your model year. The only thing that's different between models is the location of the relay.
