I read about troubleshooting and common symptoms on user James Dean's site. It's doing the thing where it engages for a second and then quits. But it has better days and worse ones where it'll engage for about 10 seconds somewhat consistently before it gives up. Today it lasted for about 20 seconds on the express lanes and I got super excited.

This is probably wishful thinking on my part, but are there any stories of it actually resuscitating completely and becoming fully functional from this condition? The car is a '92 2.6.

Never heard of a car fixing itself. Some people believe in liquid fix-it for engines like Sea Foam.

But in my experience, troubleshooting and replacement of broken parts fixes things the best.

Well, that depends on your definition of "fix". More likely its an intermittant failure. Cracked pins making contact ocxasionally, etc.

jamesdean will email a test procedure to you that will isolate your fault(s). It is easy to follow and requires only a multimeter. In my case it isolated to the actuator. He is also very reasonable if a cc amp repair/swap is required.

As a first step you may want to pop your linkage joints apart, clean and lube to see if that improves things. I also tywrapped the actuator connector in place to make sure it doesn't tend to loosen with vibration.

As to self repair, not likely although I must say mine improved with frequent use. The "surginess" went away and it now operates fairly smoothly.

Thanks for the responses. By using quasi-medical language I didn't intend to animatize the car as if it had antibodies or regenerative qualities like a lizard's tail. Also to suggest that Seafoam, which is used as a cleaner, isn't a 'liquid fix-it' is like saying there's no liquid fix-it for dirty clothes. Whether or not it works as claimed, y'all can slug that out elsewhere.

I will contact James Dean for the test procedure and see what it yields. I saw the prices on his site and they're extremely fair, so worst case isn't so bad.

Are we supposed to guess at what year and model of car you have problems with? Simple things like unevenly inflated tires or two different tire sizes will throw some cruise control systems into failure. The more info you give the better your chances are at a solution. We are not mind readers.

Mind readers? It would seem that you're not even an English reader. Last sentence of the initial post states:

It doesn't matter which '92 with a 2.6 as they will all have the same or very similar CC. In addition, nowhere did I ask for a detailed repair procedure for a specific unit, just if there is any anecdotal evidence of self-repair in a faulty CC because the function of my unit has seemed to have improved a little after repeated attempts at getting it to engage successfully. I could have added lots of little details about the car that eliminate themselves from causing issue with the CC such as that it has 4 matching tires properly inflated and all the brake lights work etc., but that wasn't part of my question.
