Is the cruise control on a '93 Lumina electrically controlled or vacuum controlled?

Question

I'm trying to fix the cruise on my '93 Lumina. If anyone has any problems in the past, can they offer any advice? Thanks in advance

Answer 1

The driver controls the cruise electrically through switch inputs and the cruise controls the throttle by way of a vacuum actuator. These are pretty easy to diagnose as all you have to do is check the mechanical linkages, vacuum supply, and all the switch inputs with a test light. This usually ended up to be the servo.
