96 Xj6, Cruise control inop, With switch to on position no light or indication on column or dash

 

Would start checking for power first. The system is powered by a small vacuum pump and is self contained. If you rule out a power/electronics issue, I’d move testing the vacuum portion. The pump is near the left front headlamp and is also shared with similar Land Rover vehicles and early 90s Audis too I believe. Check the brake switch as well.

 

I confirmed power thru fusebox

 

Oh, I was just watching a video, I do get the antilock amber light so I need to fix the module before I can go any farther , I hear solder breaking on the power input circuit is a popular problem

 

The cruise control speed input is the left rear wheel speed sensor that passes through the brake control module as a sensitive signal different then the mentioned power circuits desoldering , on its way to the cruise control electronic module

Your anti lock light come in 2 forms , inop and actively in use modulating out of a bad condition

Easy try would be to clean the brake module connector

The cruise control independent vacuum pump can be tested and lubed down the inside if frozen stuck

There is a vacuum modulator that varies the vacuum kinda like a EH valve on a autopilot

 

I think you are correct in the assumption that cruise control won’t work if abs is inop.
