Fuse Question

I have a 2002 F-250 with the 7.3L. The other day my cruise control wasn't working and i do not have a fuse box diagram. Does any one have one or know which fuse it is or if its one of the fuses under the hood?

The cruse is controlled by the PCM, but for the PCM to engage the cruise it needs
Fuse #22 20amp brake pressure switch
Fuse # 34 10amp brake on / off switch
Fuse # 45 10amp clutch / clutch jumper if auto
Also check your control switches

Does the horn work?If not then your clock spring needs to be replaced.Also check the plug on the bottom of the brake res.

ck fuses mentioned above,

check brake pressure switch on master cyl ( 2-wire switch, red wire is power, black/yellow goes to pcm ) both should have power when plugged in and off brake pedal

check brake pedal position switch ( on brake pedal, light blue/black wire is power, red/light green should only have power when pedal is pressed. i doubt this is you problem or you will have abs concerns, 4wd/low range concerns, wont shift out of park.

last but not least i would suspect the steering wheel switches are the culprit. these deal with resistance values that change with each button that pressed
these circuits do run through the clock spring that also has circuits for the air bag and horn.
