Diagnosing cruise control problems??

Ok, so here's where I'm at. When I bought my '86 the cruise control diaphragm was busted and missing, also the stalk for the turn signal switch broken. So, I found the needed parts in my local junkyard. I basically pulled the ENTIRE cruise system from another '86 incase I needed extra parts. So, I've installed everything, and.... Nothing... The d@mn thing doesn't work!!! anyone have a diagnostic procedure for testing the system? I would like to have cruise control!!! on the brighter side,last weekend the truck got new brake pads, machined rotors, repacked wheel bearings, and I finally hooked up the vacuum ball and my HVAC controls! And all of it works!

Check brake switch adjustment.

Re: Diagnosing cruise control problems??

I gave up fixing my 83 cruise. I added an aftermarket unit from Rostra. Worth every dime. My 83 factory manual has info. I don't think I have the pages scanned into PDF files. I'll check.

Re: Diagnosing cruise control problems??

I have checked the brake switch and its good... Wonder how likely it is that my switch is bad?... Or maybe my VSS

Re: Diagnosing cruise control problems??

I could use one of those pms also. thx.
My 83 cruise never worked correctly. Now it is completely dead. Everything has been replaced under the hood, and the steering column stalk is a one year only 83 unique part which is no longer available.
Used to be I could engage the cruise but it would disengage on its own unexpectedly, which would cause the gear vendor to rapidly disengage with a big clunk if I had the GV engaged with the cruise at the same time.

Re: Diagnosing cruise control problems??

In my experience it could be the cruise switch. It has solid wires instead of stranded and they break. I got another cruise switch and plugged it in without running it through the column to verify it was the switch and it worked. I’ve also seen the modules down by the accelerator pedal go out. You could probably get on for next to nothing at a salvage yard. Good luck.
