Cruise Control Quit Working

[snorindad]

I have a 2006 F350 CC LB Lariat FX4 automatic trans. I purchased the truck back in late September everything worked fine about a month ago the cruise control quit working no light when any button is pushed, horn works, changed the deact. switch on the master cylinder still does not work also #12 fuse is good under the hood. Would like to get it fixed without going to a dealer or shop all help would be greatly appreciated. Thanks in advance.

After you replaced the switch on the mastercylinder, did you bleed the brakes?

you need to replace the clock spring under the steering wheel that plugs into buttons on steering wheel. cost about $50 to $60 at any parts store

He said his horn works so it's probably not the clockspring did you check all your brake lights? I've heard cruise control quits working if one is out

I removed the master cylinder and cleaned out the reservoir reinstalled and bleed the breaks to all four wheels with fresh brake fluid and the brake lights both work also. I do not know much about the clock spring have never removed an air bag from a steering wheel but from what i have read if the horn works the clock spring is good. But will remove and check it out if you think it could be the issue.

With a good scan tool you should be able to monitor your cruise switch functions when pushed. It should show cruise on/off when pushed, etc... If you can monitor them and they don't change on the scantool screen then you have a bad switch.

Well I finally got around to changing out the clock-spring on my truck. The airbag light was flashing and the cruise control was not working and after installing the new part all problems solved. Thank you to all on ORG. I have learned a lot reading here and appreciate all the input I have received. Next project ARP studs and head gaskets and all upgrades involved with doing that project.
