1991 Jeep Cherokee Cruise Control

The entire vehicle worked fine, including the Cruise Control. I
changed the battery cable ends and everything works just
fine............except the Cruise Control. I didn't disconnect
anything that I can see, like wires, hoses, etc. The Chiltons talks
about the fuse, which was my first thought, but I cannot find the
location for the fuse, link, or whatever, anywhere. Not in manuals,
not on line. HELP!!!

A vacuum line runs under the battery to the front bumper air reservoir.
Maybe it got knocked loose?

Most cruise controls are vacuum-powered. If you knock the vacuum connection
to the "cruise control modulator" loose you get this symptom. Many engines
also have a big plastic ball to act as a vacuum capacitor for the CC, so
check that too.

To find the CC modulator, start at the carb/throttle body/fuel injector
equivalent and look at the mechanical linkage to the control. One cable
goes to the gas pedal, the other to the CC modulator.

For fuse location, I've seen it in the under-dash fusebox in a number of
vehicles, although I never looked at a Jeep. But I seriously doubt that
changing a battery could cause the CC fuse to blow.
