I have an 02 F150 it is making a weird noise. It is an annoying tick and sometimes a steady buzz. I can make the noise stop by either pressing the break pedal or turning the turn signal on. As soon as i take pressure off the the break or shut the turn signal off the noise starts again. My mechanic has tried a new break switch and some new wiring but hasn’t stopped it. He is kinda stumped and i am tired of it. thanks hope to hear from you soon…

Does the 02 F150 have a LCM? If so, it might be one of the relays in there buzzing, which would indicate a fault with the LCM or the wiring to it.

That would be a Lighting Control Module, not a Lunar Control Module.

And I think Tardis’ suggestion is an excellent one.
