95 pete 379 cruise control problem

Did you replace the clutch switch like I stated earlier ? The brake switch I reckon would be only if your brake lights weren't working, but not 100% sure.

 

Will the brake lights still operate even if this switch goes bad? My cruise quit awhile back. It used to be intermittent. Then one day it quit, I reset it and about a half mile later it quit again. Six times like that and it just quit period. The only thing I haven't changed is the brake switch, clutch switch and harness. I'm running out of options. It'll throw a code but all it says is switch failure.

 

There are two seprate brake switches, one for the ecm and one for the brake lights. Clutch switch is the most common. Year/ vin.
High idle work?

 

do the jakes work?

 

Im Chasing Mine Also.....But I Went Further, I Replaces Clutch Switch- Speed Sensor- Cruise switches(on/off set resume) AND Clockspring.. STILL NO CRUISE- Will Not Kick idle up-Nothinh-

I Did Not replace Brake switch Because Brake Lights work and no air leaks.

Its a 2001 FORD with a C12. Now, Last Nigt I used a Screwdriver to Up the Idle while I Slept (pryed it between the Dasah and Throttle pedal... In The Morning, I Removed the Screwdriver But it stayed idled at whae I Set it at last Night..I Had to hit the "Off" Switch to go back down to normal idle.

Is Thewre something in the accelerator Pedal Sticking For Cruise ??

 

1992 Peterbilt 378. First start it up you can set the cruise to idle. Once you apply the brakes and start driving all cruise options shut off. What is the problem??

 

Replaced brake switch and clutch switch and once I reach 65mph the cruise control cutoffs

 

I know this is an old thread, but my cruise will only work when brakes are pressed. Brake switch bad?
