i have an 86 K5 with cruise and sometimes it works, sometimes it doesn't, it's like a blinker handle on the left of the steering column, has a push in button at the end of the handle, a button that pushes in twoards the steering column and there's also another switch, i don't know if it's a switch but it's on my winshield washer button. for the winshield washers i push the button forward and i can also pull it twoard me..does that do anything?? my question is how to get my cruise to work? what buttons to push? sometimes it will just start working when i'm playing with it, and other times i can mess with it all day and it doesn't work? anyone have any tips or suggestions on how this crap works?
