I noticed a few weeks ago that my rear view mirror keeps "resetting". When it does this it looks like it does when you first start the truck. The compass and temp display ***, the green power light turn on and off, and the passenger airbag "on/off" lights also turn on/off. It only did it a few times and stopped. I have not noticed it again until today. It started doing it every 5 minutes or so. I am wondering if this is a common problem and what the cause may be! My 03 Yukon XL did the same thing. On that truck it was consistent with it being hot outside (above 85 degrees) and when it would "reset" it would do it constantly. When it was cold out it would act as expected. Could it be the temp sensor? Any other ideas? Thanks
