The CC inorder to work, the brake arm has to rest and push in the switch for CC to operate. If you have a gap between the plunger of switch and the upper brake arm the CC will not work.
The brake arm as it is used will wear a beveled edge on the plastic plunger so I added a sticky rubber strip to prevent the wear and fill the gap.
The gap was filled in with a piece of sticky back rubber 3/16" in order to close the switch.
If you run a dollar bill between the plunger on switch and the upper brake arm with no reasistance the CC will not work.
While your driving and using CC the upper brake arm is pushing in the plunger for CC to work.
As I said its very differcult to work on this and you have to work by touch to check that gap and put on rubber strip.
Be very careful because you are also working against the brake pump when pushing in plunger and down on brake to do all this.
This switch on mine controls the electric steps,lights, CC and brake pump dependant on what action the brake pedel is operating.
