Where is the relay flasher on a 2002 Ford 150 Super Crew?

The turn signal flasher relay on a 2002 Ford F-150 SuperCrew is typically located inside the under-hood fuse box. It's not a separate, easily identifiable relay like some older vehicles; it's often a small module integrated into the fuse box itself.

You'll need to open the under-hood fuse box (usually located near the battery) and consult the fuse box diagram on the inside of the cover. The diagram will show the location of the flasher relay, which may be labeled as "Turn Signal Flasher" or something similar. It might be a small replaceable module or even just a section of a larger module.
