Where Should I Look for the Flasher Relay on My 1997-2003 Ford F150?

If you have an older eleventh generation F150 from 1997 through 2003, the flasher relay is most likely located on the right side of the steering column. Here are the specifics:

Check near the relay block – The relay block is a rectangular plastic box attached to the steering column housing. Carefully remove the relay block cover to access the relays inside. The flasher relay may be among the several relays in this block.

In the twelfth generation F150 produced for model years 2004 through 2008, Ford moved the flasher relay location. It is now typically found under the dashboard on the right side:

Behind the trim panel – Remove the right side dash trim panel and look for a small relay box attached to the underside of the dash, above the hood release lever.
Inside the fuse box – On some models, opening the fuse box cover reveals the flasher relay among the fuses and relays inside.
Behind the glove box – On F150s with the floor-mounted automatic shifter, check behind the glove box for access to the relay box.

Consult your owner’s manual to pinpoint exactly where Ford located the flasher relay on your specific truck. Use a flashlight to illuminate the relay box.
