The switch might be bad? the "on" side works but not the "set"? If you have no vac leaks.

Vaccuum reservoir under the front right headlight. A small crack means no cruise and your vent position won't change off defrost

Ok been reading this and I have no cruise but my vents do change. If there was a vacuum leak would it not run rough? Mine smooth as silk. Haven't really dug into this yet as most of drive is on congested roads.

If you have the AZC dual climate, then the mode door is run by electric motor.
I have had a vacuum line fall off of my throttle body and it idled perfectly normal. More than likely, you have a vacuum leak, but it's not the only problem that can cause cruise control to stop working.
We just start with the easiest.

I'm having a very similar problem after doing the head gaskets on a 04 4.7HO. The dash lights work, all of the vacuum lines check out, the cable is hooked up to the TB, but still not cruise control.

After the rebuild, I didn't have the cable hooked up properly and I found it loose at the TB. At first, I thought it had moved to set and popped off, but I now think that the TB cam moved and the CC cable stayed in place and popped off. Reattached, but it still didn't work. So I went back in, pulled the battery tray and inspected all of the vacuum lines - everything looks ok.

Can't figure this one out.

I'll have to try and post a video of my CC cable at the throttle body - its very loose and im not sure it should be. Do other people have a lot of play in this cable?

Is this a possible clock spring issue? That particular metal thread is broken for the set of cruise but the ribbon has connectivity to the other items?

I do (but mine isn't working either), but I've also read that it's common to have 1/4" of play in the cable between the TB mount and the TB cam.

04 WJ 4.7 SE Cruise control

Hi everyone,
I just subscribed to this website and wondered if anyone can help me with this one.
Should the two hose connectors in the back against the wall be connected? Could this be the reason my cruise control doesn't work?
Side note, they are quite greassy?

The one on the right looks like the valve cover breather fitting. There should be a hole on the back of one of the cylinder heads where that goes. It will match the other cylinder head. Pop that back in place but it will not affect operation either way.


The other one, yes, that may be the issue. I do not recognize it, so trace it back to it's origin and that will help us tell you where it goes and what it does.

When my CC went out. All my vents worked perfectly. The first time it was a deteriorated vacuum hose under the battery. Replaced the hose and it was fine. I kicked on the CC the other day and its not working again. But all my vents work. Mine is a 2000. I disconnected the vacuum hose at the throttle body and I have vacuum off the connection there. I blew into the hose and I can hear a hiss, from under the battery. I guess thats where the leak is. But my point here is, each time, I had no issue with the heater vents working.
