Is there a tech #? I can’t find a number to call for GM harness connect cruise issues. Thanks
Good luck dealing with GMPP. I had a horrible time with them on the phone trying to deal with a warranty problem. I also could not find phone numbers anywhere, so I called Jeg's and they gave me a number which at least was a start. If you are on Facebook you can send them a PM.
