The cruise control on my '92 usually works fine, but every once in a while will cut out (usually when a tractor trailer is tail-gating!). It seems more likely in cooler or damper weather, but it may surprise me at any time. The electrical connections seem fine, and I replaced the vacuum hose, although the old one was fine, and it was clear. I've also tried different ports on the manifold, all to no avail. My next step is to replace the unit, but if this isn't the problem, I will have wasted money and not fixed the problem. TIA for any ideas.

I've got a cruise control servo (or whatever it's called mounted to the fender) from a '93 XJ if you need it. [email protected] . Sounds like the problem to me but I'm not positive.

Have you verified with a pump and gauge that the system is holding vacuum?

Hey dude I have the same prob in my 91. Whenever it cuts off I just reach behind the little control arm and jiggle the wires at the base. That will get it going again for awhile until it decides it wants to act up again. Worth a try... hope that helps

A similar thing happened to my Dad's Saab - it was cured by getting a new cruise control switch from the breakers.

I replaced my signal arm and that cured it.

Thanks all for the responses. I swapped the servo from my son's '95, and it worked fine for about an hour, then it started acting up again. The vacuum end of it is fine.

the wire to the switch is bad for breaking going in the steering column. about 50 bucks for a new switch.

there is also a wiring diagram in all manuals to check the switch in all its positions.
