My side view mirrors use to automatically adjust down when i put the car into reverse but the other day it stopped doing that, maybe a bad fuse or did i accidentally hit a button?

 

Go to the right drop down control panel. Open it and make sure you hit L or R for the right or left mirror signaling. Make sure there is a green light on top of the L or the R. Then it will go down in reverse.

 

In brief, read your Manual before asking.
You will find there a lot of answers on f.a.q.

 

Works , Thanks.

 

I've read my manual and I am very familiar with this feature in my Range Rover.

While the driver's side mirror auto adjusts downward when in reverse, the passenger side mirror seems to adjust downward only some of the time.

I always use the same key and my have programmed my driver seat memory settings to auto adjust when my key is detected.

Any ideas?

 

Yep, it's broken. If only one of them does it... gear inside got stripped. Common problem.

 

Ahh thanks...i knew my driver's side side-mirror is messed up bc i did the instructions in the beginning of the thread and the mirror still only went down half way. So there is definetely something wrong.

Where can i get this fixed and how much would it cost?

 

The only thing you can really do is replace the whole mirror assembly, which is expensive in the 08+s. I don't think anybody has really figured out how to "repair" them, but you can try disassembling and trying to source a gear of the right size and shape but that may be difficult. Lexus does not sell anything inside the mirrors as a separate part.

 

hmm...I wouldn't dare try it myself. But i have an 06 GS
