Prelude
Have you ever taken anything apart and wished you had taken better notes or photos? I have.

This post is part of a continuing series of posts that detail the internal construction of various things. This is not intended to be step-by-step instructions for repair/removal/disassembly/etc. Rather, I hope this post (and future posts) can serve as a reference for people who would like visual clues in making their own repairs.


Little Notches
These notches (circled in green) are accessible by pushing the glass of the mirror itself all the way to one side and reaching inside the housing with a pick or blunt screw driver. Using the notches, rotate the black plastic ring a few degrees until it releases the mirror glass from the mirror housing. Lay some towels or a work mat on the ground to provide a degree of protection for potentially dropped mirror glass.

Lubricate the Two Drive Motors
Completely eliminate mirror whine noise by lubricating both ends of the two drive motors. I used a silicone spray lube. You use what you like. Connect 12v power to the proper pins to run each motor through its full range of motion (or use the mirror controls if it's still on the car). This can be done without removing the mirror housing from the car. Only the mirror glass needs to come off.

Remove Wires from Connector Body
I used a pin removal kit from Amazon. It contains many thin walled stainless tubes of different diameters, plus some thin reaching tools.

Hidden Allen Head Fastener
Swing mirror out of the way for access. After this, the mirror housing can be removed from the car. New gaskets where the mirror housing attaches to the door are still available and pretty inexpensive. The old ones will be brittle and crusty.

If You need to keep going...
There is a "triple square" fastener in there. This is the one that often comes loose over time making owners mildly paranoid about folding their mirrors in. You can use a 3/8" Allen wrench to remove the fastener. It is under spring tension and is challenging to reassemble. Use threadlocker and get another 20-30 years of reliable mirror folding.
