84K10 with cruise control and delayed wipers. It has the electronic eye thing that goes in the back of the speedometer. I searched and found some info... but not what I was looking for. Please bear with my stupidity found below. I've been trying to chase down this cruise control problem for months. So far I have swapped out the module (the thing above the accelerator pedal) and tested/swapped out the vacuum/electric switch that goes next to the brakelight switch. The smartstick/stalk was replaced 6 months ago because it was believed to be bad and it was replaced a month ago and I don't think it was bad either. I'm going to replace it again tomorrow. I hooked up a solenoid temporarily and drove it down the road just in case mine is bad. The solenoid doesn't appear to ever get power to it. The speed buffer thing... I think I've replaced that once and it didn't do anything. Should I try it again? I'm sure I have another one laying around somewhere. Does anyone know what wire(s) should have power to it? At what times? Where it gets its power from? My manual is as useless as a screen door on a submarine when it comes to cruise control. I figured I'd give tracing wires a whirl but there is a buttload of wires to trace. A schematic would be very nice because then I could make sure all of them were working without following them physically.
