cruise control

[Ron Coleman]

i changed the cc stalk because i thought that was the problem after reading the archives but no luck
my switch at the pedal works but i have no vacuum at the switch .
i hooked up a mityvac to the servo and get no vacuum at any speeds

anybody what can cause this?
could it be a bad servo unit!?

thanks

Do you get vacuum from the cannister line directly connected to the servo?

Vacuum valve must be closed from electronic control to get outlet vacuum to the brake line hose.

Could still be electronic/switch wiring in nature.

Light green wire at servo should get +12 to operate the valve in question with cruise on.

Does the indicator on the dash light up?

Brake switch has an electrical cutout as well that is normally closed to operate the cruise, when you hit the pedal it electrically opens the circuit.

Wires are brown and gray to it, A and B terminals at the brake switch.
