I have a 2015 2500HD LT manufacture 3/2015. It is a AVF minus A45 and came with DPN mirrors. The truck also had the 23171572 & 23171566 harnesses. I am switching to DSQ mirror due to garage door opening clearance. I have installed the following:
23241465 & 2324167 mirrors
23488411 driver side powerfold switch
23147589 switch harness. It is the memory compatible wiring but the only one the fits the switch connector.
23245541 passenger window switch
23147593 passenger switch harness
The original functions of amber lights and cargo/LED lights work. BUT, no power fold or power adjust. I noticed that only a few of the pins in the 23171572 & 23147589 connector ends mate in active slots.
Have I missed a part or do I just need a BCM flash.
Thanks for your help.
