1984 Corvette Cruise Control quits when warm
I have a 1984 Corvette that I've rebuilt and I'm working on the cruise control. When you first start driving the cruise control works fine, but after about 15 minutes of driving at highway speeds, it quits working. The 700R4 transmission was rebuilt and the speedometer always works fine. The turn signal lever is new and all the voltages work. I just installed a rebuilt cruise control servo assembly. Almost all of the vacuum lines are new and after it quit working today, I removed the brake sensor vacuum line at the servo and capped it. It still did not work while the car was warm.
