No cruise control

i remember that happened to me but i was a company driver and never took it to the shop i aslways slammed on my brakes on the highway then it would start working again

 

Blown fuse.

 

Could be clutch or brake switch. They will disengage the cruise from working.

 

My bad there is no fuse for cruise. Maggard has the best idea Could be the cruise switch, brake switch,clutch switch,park brake switch.

 

have you tried pulling the pedals up with your foot to see if it will work then? Sometimes the return springs get weak or break and the pedal doesn't return all the way up, keeping the switch open and not letting the cruise work. Usually the clutch pedal.

 

I would definitely check the switches be the easiest. Other wise probly something with ecm.

 

The columbia cruse is glitchy. I think the ECU gets hung up when it gets a bad indication, even if the sensor now says it fine.

Heres what i found to make mine work 99% of the time.

NEVER start the truck with the cruise switch on. Always turn it off before turning truck off. On after the truck is running.

If you do leave it on when starting, you need to shut it off for like 30 seconds then turn it on. (more likely to have problems)

If it still doesn't work.....hit the brake, then the clutch, then the trailer brake handle in that order. making sure each one seats to it fully out position. Trailer brake was the main culprit on mine. dont need to push um in hard, just enough for the sensor to relize you were on them and are now off. Hope this helps.
