Ok, so I had some time today to put these on. When I first plugged it in, only the driver side folded as you said. I reprogrammed the DDM (driver door module) & the BCM. Now no mirrors fold. Everything else works. I had a message while programming saying that if I'm using different mirrors, I have to call tech line to get a VCI code for special programming. IDK, I'm not too familiar w/ GM stuff... I work w/ Nissan at my dealer. Working on GM's is like my last resort, so I don't get to work on them as much as I used to LOL! If you're experienced in this maybe you can shed some light... Thanks.
