Cruise control not working

2008 jeep grand Cherokee v6

I'm moving the lever, bottoms and looks like the cruise control isn't connected or something in wrong some where

No lights

No codes

No check engine

Also I found this connector

Is: green / blue line & green brown

Scan for codes they will not always set the light. Also misfires will disable cruise

That connector doesn't look like something a cruise control would use (too big, and not enough wires). I would think it would be very fine wires or one of those circuit board looking tapes, and I wouldn't think it could possibly do on/off/accel/decel/set with just 2 wires.

Did you look for a fuse? Mine looks different than yours (07 here), so I'm not sure how much help I can be. I just looked at my manual and didn't see a fuse for cruise control, so either I missed it or it's combined with something else.

A couple things, which I doubt your jeep cares about, but worth mentioning: I had a Lexus that would not set the cruise if the wipers were on high or if the transmission selector was limited to 3rd gear or so, or if you were going below about 30mph. I don't know if you were trying in any of those conditions anyway.

Check the brake lights. If the switch on the brake pedal fails or is out of adjustment the cruise will not work.

You're kidding, right? I'm going to play along. Your cruise control doesn't work at zero mph? Yes it does. It keeps your vehicle at zero.

I've never owned a vehicle that would set the cruise at speeds below 25mph (usually a bit higher).

In your case, I believe the problem is a simple replacement part, easily found as there are about 6 billion on earth. Behind the steering wheel, you will find a large nut. Replace the nut behind the wheel, and your vehicle will be better off.

Sorry if I've made a mistake, or if you were simply being responsible and not taking video while driving, but I'm drunk and I have brain lesions. In any case, you responded to a post suggesting checking the brake lights to see if they are stuck on, and your response is a video of you sitting still and abusing the cruise button.
