I searched through all the menus and looked for a switch I might have hit, but I don't see where I could have accidentally turned off the automatic windshield wipers. NOTE! That doesn't mean I didn't do that! LOL. Just that I can't find it. Anyone know if this is a common failure for a 2014 LS 460?

 

If you're talking about the rain sensing feature, the windshield sensor may be the issue. Especially if the windshield has been replaced or the señor removed and reinstalled.

 

On the wiper control arm. Turn the dial to Auto.

 

Yeah, It does indeed have what appears to be a replaced windshield, however, the sensor worked just fine for over a year. Then suddenly stopped working.

 

Check the fuse for the sensor.

 

My Auto wipers stopped working too. It turned out to be the clear plastic adhesive pad between the rain sensor and the windshield (the rain sensor is mounted to the windshield behind the mirror). This clear plastic adhesive pad over time gets cloudy (from the UV?) and the rain sensor no longer “sees” the rain drops. The replacement part is #89944-50021. It costs around $20 on Amazon. Changing it fixed the problem.
