Cruise Control issue

The cruise control on my 08 GC Limited sometimes doesn't work--the "cruise" light doesn't go on & it doesn't engage. After an engine on-off cycle or two, it works again, & will work until I shut the car off again. Then, it may or may not work the next time I start it up. Is there a way to re-program it?
Thanks,
Roger

Re: Cruise Control issue

Re: Cruise Control issue

Air seems to work fine, as does everything else. I was thinking it might be one of those things that needs to be reprogrammed occasionally, like the automatic up on my drivers window.

Re: Cruise Control issue

Mine will only work if I'm above a certain speed but that's how they designed it.

Re: Cruise Control issue

I am having a similar issue. You can activate the system but once you go to set it, the dash light goes out and you cant get it to come back on til you restart the vehicle. It seems like it's looking for some kind of input from a sensor that it isnt seeing, so it just shuts off.

I have yet to find anyone's resolution posted online. My internet searches suggest various things from brake light switches (mounted at the pedal), to cruise control servo motors and their vaccuum lines, to pcm replacements.

My 2 cents is it is probably something mechanical as virtually anything with a plug-in on these newer vehicles is tied to the computer and you would get a failure code..

Anybody else have input?

Re: Cruise Control issue

mine stopped working after I broke a few connections on a main harness under the hood.

Re: Cruise Control issue

My cruise switch stalk stopped working similar to the OP's problem. Dealer replaced under my 3/36 warranty.

I have a 2011 Liberty, exact same problem. Have had it to the dealer multiple times wit no resolution. Question about the AC has me curious, as mine seems to blow cool but not cold. Could these things be related?
