SC430 2005 Mirror Switch
I've got a 2005 SC430, and did not find much under that category. The issue......mirrors worked intermittently, then both just went completely out. Don't work in reverse either. My switch comes out slightly different from the LS, but essentially sliding the plastic tool under the bottom of the panel holding the switch, and worked my way around and slid right out. Not much room to manipulate the wires, but found if I removed the mirror connector first and security connector second, worked pretty smooth.
So got the thing apart....zero corrosion. Kind of rubbed the grease around and reinstalled. Nothing. Read a bit more and found others that had zero corrosion, and cleaned the connectors. So pulled it apart again, used isopropyl and as far as I can tell, the grease was the issue. The connectors had sort of a matte finish before cleaning, and after cleaning they were mirrors. Put the thing back together, and blammo..........works. I'll pick up the dielectric grease later today, give it a light coating, and button it back up. For those who are not using the grease, yes the switch is not used much but to prevent further corrosion and wear, I'd highly recommend using the grease.

2005 LS430 – My power mirror adjustment switch is working intermittently on both the left and right mirrors. It started on the right only but within a few months, it is now affecting both mirrors. Anyone have this problem?... What was the fix? Any switch repair / replacement wizards out there?
