some examples of locations cruise/brake switch

Try checking the small switch at the top of the brake pedal. There may be two one for brake lights and one for the cruise control. To ascertain what is what, pull one wire off and see if brake lights work. If not, then the other switch controls the cruise control disconnect and engage..I you have a DC test light check to see if power is on on both side of the switch with brake pedal up. If so, depress pedal and check power on the other side there should be none, if there is the switch is defective.

If the switch is replaced,then it can be wiring issue or faulty cruise control board.But as the switch is replaced,get the voltage at the switch tested to confirm the switch is actually receiving voltage.If no voltage received at switch power supply wire then ,apply external 12 volt power to the cruise control switch wire and then see if cruise control comes ON.If yes,then you know wiring is issue.

are you going uphill in overdrive gear . If the speed is lower than you set the crruise control might disengage. ?

The brake light switch & cruise control cut off switch are incorporated together by the brake pedal

The Venture uses an electronic Cruise Control and doesnt require vacume. I would suspect the cruise module under the hood, or the lever on the steering colum to be bad.

First, your car must be in gear and driving approx more than 60 km an hour
Secondly, using the Cruise Stalk switch turn the Cruise on, the dash should now have a lit icon for cruise power (green).
Once you have the desired speed, gently press the button on the end of the cruise in to set your speed. Remove foot from throttle and confirm cruise is active. Another dash light should come on as well (orange)

Failing that, if it doesnt work the usual suspect like fuses and the brake pedal micro switch should be looked at...

You have a short somewhere dude

Usually cruise controls go out after 10 years. Probably not owrth trouble
