My right mirror motor was acting sluggish which I believe it was the motor acting up. I bought a new one from the dealer and when I opened the box it was a repair kit, it had the wires to splice to the existing wires. I managed to hook up the wires by their color and tested it and it didn't work. I checked fuses, the control switch and the memory control unit is good. Using the wiring diagrams from Mitchell1 DIY, I checked wires for continuity and all of them checked good, I checked for power coming in the control unit and is good but I didn't get any voltage going out to the motors at all. I noticed in on of the wiring diagrams that one wire coming out of the memory control unit goes to the Computer Bus Data Lines. Does this mean that the dealer would have to program the mirror with the GT1 computer?. Or is it possible I have a mirror motor bad from supply?

The LIN bus that controls the mirrors does not require programming or coding. It is possible the motor is at fault.
