Cruise Control Fuse?

Is there a fuse for OEM Cruise control on a 2001 TJ?

I've got cruise control on my system, when I turn it on, the dash light comes on, but it goes off and won't come back on until I turn the vehicle off and back on.

I'm trying to troubleshoot it and figured the best place to start looking would be a fuse, but I can't find anything.

what else should I be looking for?

Maybe I'm not setting cruise control correctly.....

When I purchased mine (05) the c ruise wouldn't work. I had a vacuum line disconneted on the drivers side that caused the problem. Hooked it up and works

Dont have any pics but I had the exact same issue when I purchased mine. Brought it back to the dealer to get it fixed under warrenty and they found a vacuum line that had disconnected and once they hooked it back up it worked fine.

Those are good.....look inside the bottom of the passager front fender...a vacuum line goes into it into a "black box" inside the fender. TWO most common and they are a common issue.

I concur what distorted said, check the vacuum line. It might be something as simple as the vacuum resevoir being cracked or a disconnected or leaking vacuum hose...


here are some pages I copied from my service manual. If you find out that you need to replace the servo, I have a perfectly good one that I removed from my 2004 TJ that you can have. Let me know.

The manual also documents detailed steps to perform these diagnostics. Let me know if you'd like me to attach those instructions.

Failure of switches on steering wheel to make good contact is a common problem.
