The passenger mirror part of my 2011 Denali XLs sideview mirrors re-adjust on its own only when the car isn't running. It is very irritating. Why does this happen?
the memory is set for the prior owner look in manual to see how to reset it.
set the mirrors where you want them and then press and hold the number one button on your driver's door down until it beeps twice- then repeat the process with the nuimber 2 button and it will stay where you want it to. I hope this helps
