If you haven't check the fuse yet, its number 6 fuse, far right top in fuse panel left of steering wheel, above hood latch release. Also check if actuator cable is still attached at TBI. Other than that, it coulbe switch, or could be Cruise Control brain itself. You can check if its switch w/ multimeter by disconnecting connectr hook 12v to the positive feed and try the different functions. If its working, you will see meter movement each time you perform a cruise function. To determine which is the positive use multimeter to find 12v from other connecter that goes farther under dash (not from streeing column), w/ switch on, engine not running. (assuming you located and checked all fuses to be good.) If switch works (and I am assuming it will, I have had 4 GM vehicles, all w/ cruise. And of those four, only two did cruise not work. First one '84 Buick Skyhawk, I replaced everything but the vacuum assisted servo, another '86 Suburban - that was easy fix, reconnect actuator to throttle linkage at carb.) then suspect servo/brain unit. Good Luck. R/ Al
: There is a conector below the dash for the cruise control, it is a wierd flat into a circuit board type theing (kinda like a computer USB conector) and if I remember correctly, there is orange plastic involved.
: Point is that you can disconnect the existing one and attach a new one without fishing the wire down through the steering column (major pain if you forget to attach a pull string before removing the old one!)
: Just put a new one in and let it hang down and take it for a quick road check. (use caution when doing this) -if it works thaen you can proceed to change out the old with the new.
