Hi all, my first post on this sight,
I have a 2017 Silverado LT+ and in process of up grading from DL8 to DL3 mirrors. I have brand new take off' with harness & mirrors from a zero miles 2016 diesel Silverado with left 23342732 harness & rt 23342722 harness with the 23154702 switch, the results are no power fold & drivers mirror adjust only worked up & down only, pass side no function on mirror adjust, all other functions worked all plugs match correctly, just as "pgamboa" stated. My thoughts may be a BCM flash if even possible with the new production, I can here what sounds like a protection limit clicking out inside the switch housing when I try fold, then I must on & off the power to get a reset. I am just exploring this what appears as a doable upgrade, as I was told the General has most functions in main harness factory wired to the "A" pillars. Any thoughts on this would be helpful....
