I'm scheduled to have the ground wire replace on my 2019 new body SLT .... now I think I should wait

On my early 2020 GMC Sierra SLT ( actually a late 2019 new body ) I have an ongoing problem with my passenger side mirror. This mirror was replaced shortly after purchase for going to extremes and clicking. It then worked fine for 5 years .... Now it starts searching for position every time I would start up the truck. On very rare occasion it will start and actually go to my memory setting. Please don't tell me how to reset the memory .. it's been done so many times my finger is getting tired. I've also disconnected the battery multiple times. I don't know if this helps find a solution: When I start the truck and the mirror moves ending looking at the sky or road .... I've tried to press driver 1 and or driver 2 ..... nothing changes. The truck has been to the dealer multiple times with NO SOLUTION ... The dealer has told me this is not a new problem to them and they have no long term cure ... Anyone here have a fix?
