95 maxima cruise control problem

I have a 95 Maxima & I am having a problem with the cruise control, I
have replaced the actuator vacuum servo cable, vacuum servo motor, the
cruise control module, & checked all the fuses, relays & all the wiring
checks good. The ON switch on the dash lights up but the CRUISE light
inside the dash will not light up or engage when I push the SET button.
I also replaced the set of cruise control switches on the steering wheel
with a used set I think they were a good set. Any info would be helpful.
Thanks
