Exact same process must replace bcm with uplevel and follow the directions to the T or it will not work correctly and the rear windows on the truck will not work correctly. Major PITA

01WS6/tamu I have a 2007 classic Silverado LT with the power folding mirrors and want to install a set of the power extending mirrors from a 2004 LT. The mirrors will extend, but will not retract. What is necessary to make them retract also?
Thanks in advance!!!!

Probably need to reflash the drivers and passenger door modules for correct option code for power extend haven't ever messed with power extend towing mirrors. Only DL3 signal/power fold.

Couple questions... I have a 2012 GMC Sierra. Since the harnesses that plug into the bottom of the window switch are different from the window switch that has the power folding mirror (pic below) I need the different harnesses that are for a databus wired truck... correct? Will these harness just need to run from the BCM and to each new switch? (I already have the driver but I will need the passenger too if I am reading correctly...)
Also, if using a Tech II scan tool do I still need a vin from a different truck with the power folding mirrors optioned from the factory?
What exactly will need to be reflashed aside from the DL3 mirrors (radio? BCM? rear back up assist?) Thanks again and this is a great and extremely helpful write up you have done.

Changed all of those parts. Then I reflashed the BCM, DDM, and PDM to the VIN of a truck that had DL3 option. You then have to reflash the radio also because it is VIN locked to the truck and will lock up with the bcm reflash. If you have XM radio the XM will lock out. There is no way to relearn it you must replace the XM receiver with a new never programed receiver. The new xm module will then learn the vin of the truck with the DL3 option once it is installed and the new receiver setup procedure is done using the tech 2 under the special functions menu. Once the bcm is flashed you have to go to special functions in the bcm and select SDM relearn so the airbag will function. EDIT IF your truck has rear park assist this module must also be replaced with a brand new never programmed module because it is VIN locked to the BCM just like the XM module for god know what friggin reason.
Thanks so much
