Hi,
So my 7.3 has been making a solenoid/relay clicking noise and I tracked it down to when I move the BOO switch on the pedal.

Basically, I can make the solenoid clicking noise inside the dash go away or go crazy by slightly moving the BOO switch.

Any ideas on what I should replace? Is it just as simple as changing the BPP or is it possible something else needs to be replaced?

Thanks,

CnB

I always just called it the brake pedal switch, ...Kids and their acronyms

Figure which one is causing the relay clicking and replace or adjust that one

Hi, thanks for the reply鈥

Question:
I know when a wiggle the BPP switch (the switch connected to the brake pedal) I can make the solenoid/relay stop or go crazy.
Does this mean the BPP switch is the problem, or is the solenoid likely the culprit?

Your pedal going all the way back up to the stop ?

move the pedal side to side and look at the bushings on the pivot shaft -- not common, but they can break
also check the return spring

Yup - all good.
The only issue is the solenoid/relay clicking I can make happen or make go away by slightly moving the BPP switch attached to the brake pedal.
