I have a 97 3500 that I cannot get the cruise control to work.
I have followed all the troubleshooting in the factory manual.
New clock spring and control switches.
The little green light will light up (but you cannot turn the light off until you shut off the truck)
Using a snap on scanner to read the
PCM the buttons do exactly what the service manual says they need to do for voltage.
The servo is connected and tests out good. You can hot wire it and get it to function.
The wires all have continuity throughout the entire system.
I am stumped! Could the
PCM be junk?
I followed the factory service manual troubleshooting step by step and technically it should be working.
