Help--Cruise control doesn't work.

[jvencius]

For the last few weeks, my cruise control hasn't worked and now I'd like to fix it. Background info: I've got a 2002 F-350, 7.3 PSD, ZF-6. I replaced the bulb in the center high-mounted brake light, but that didn't fix the problem so what should I look at next?

The fuses checked out good. Where is the brake pedal switch and how do I check it? The brake light does light up when I push the brake pedal.

the brake switch is actually two switches, one senses brake activation and cuts off the cruise, the other sets the lights.
need a schematic to know which side of the connector to test.


i cant get the pdf to pull up-mad , pm bill and ask if he can shoot you a copy of the page if he has it maybe

Is there a CC sensor somewhere in the driveline that could have gone bad? I suppose it's also possible that the switches in the steering wheel have gone out...

well, there's the VSS on the trans that could be jacked, but the speedo wouldn't work either...

dude, ya need a schematic and a test light... guessing is just gonna waste your money and annoy your wife..
