I just picked up a 2006 F-350 and the cruise control isn't working. I did some research and replaced the brake pressure switch and that did't fix it. Looking in the manual there is no fuse for the cruise control, and am guessing it comes strait from the computer. there are no other lights on the dash and the horn works as does the climate controls on the steering wheel. where else should I focus my trouble shooting ?
There's not much to it. As you said... straight from the PCM. Might start by looking at the J1-C1 connector on the PCM. Otherwise, it's switches and resistors.
You can find a wiring diagram for your truck here:
On my 03 the cruise would not work at all either. The more I messed with the buttons while driving it started to work. I can now get it set, sometimes get it to accel, but won't coast. I would bet your switches are like mine and just need replaced.
Does the horn work? Radio controls? Could be the clock spring.
Edit: Not enough coffee this morning. I now see you said the horn worked as well as the climate controls. Still "could" be the clock spring, but not as likely.
from Ford the clock spring is $335 and the cruise control buttons are $325. Guess I will have to do more troubleshooting before I bite the bullet on those parts to be as sure as I can.
Do the buttons feel OK? My wife's steering wheel controls were all goofy...found that something was spilled on them in the past, so they were sticky and didn't work correctly. Got some electric cleaner spray and it fixed the problem.
As of now all the buttons light up. Currently only the climate control buttons work, but there is an aftermarket radio installed and I don't know if they installed the steering wheel controls adapter. Will find out soon though.
Final update, cruise control is fixed. Decided to bring it to the dealership for this and the upfitter switch issue I was having. Turns out it was the cloth pedal switch. It is two switches in one, one for the starter and one for cc. Replaced the switch and now I have cc.
When I got my dads 94 f250 the cruise didnt work. I replaced the brake switch and no work. I started pushing the buttons on the steering wheel and after about 50 pushes it started working. Works fine now. I guess my dad never used it.
