      My ’93 GMC Savana cruise control is not working & since this is our main vacation transportation, it’s really a pain to maintain a constant speed on the highway. This van sat for several years with intermittent use. I’m not sure what is a good starting point on troubleshooting. The servo that actually operates the throttle on top of the motor is NLA. I need some suggestions – BESIDES buying a new van. This is a nice, low mileage van and I want to keep it.
