Cruise Control problem

[fishhunt22]

I'm having a problem with my cruise control. I checked the fuse and tested the air bladder by the throttle cable under the hood. Can anyone point me in the write direction?

Could possibly be a vacuum leak. Follow the vacuum line that attached to the rubber bladder in the engine compartment to ALL the connections and make sure there are no vacuum leaks. This is a starting point.

Recently, I was helping a Discovery I owner try to locate the best place to fit a Hella light wiring through the bulkhead and low and behold on our company Land Rover the "Y" cruise control line junction (near the bulkhead and brake booster) appeared to be normal until I touched it... .

The vacuum line was cracked on the underside.
