Side view mirrors tilt down on reverse

I have mine set to tilt down when I shift to reverse. In the beginning it worked fine both moved down equally. Now randomly the right side tilts down as normal and the drivers left side moves down maybe 25% of what the right side does. So the driver side tilts down for maybe a 10th of a second while you can hear the right side tilt down for a couple seconds.

Any thoughts? I plan to have the dealer look at it. I plan to have the dealer look at it

 

If im not mistaken, you can adjust each one independently for how far down it tilts. so if one has changed, maybe you accidentally adjusted it and now it tilts down less as a result?

switch mirror toggle to drivers side, put it in reverse and adjust it to where you want it to adjust to, I think should fix it.

 

Bingo! Thanks for the help. Feel like a dope now. You were exactly correct in your explanation.

 

No probs, glad I could help
