Passenger side mirror unfolds too far

Hi, I have the same problem with Lexus RX 450, did you fix yours? Thx

I join here, I have the same problem since I hit the mirror in reverse. I have disassembled it and find nothing internally broken. But still it goes completely forward when I actuate the electrical mechanism.

My magically stopped swing all the way forward, worked properly for a year but now started turning about 30 degrees too far, no longer all the way. Still no good solution. I did read that there is a cheap thin metal washer internally that needs to be reset or replaced. I have also taken it apart but haven’t cut into the sealed black plastic motor/gear casing.

Did anybody figure out a fix for this? My drivers sideview mirror goes all the way forward when I start the car. I have to manually bring it back. Or quickly hold it so it doesn’t move forward.
