Diagnosing cruise control problems?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

fanmanj · 02-29-2012, 12:49 AM

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.

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.

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