I miraculously got it back together, not without breaking half the tabs and what not. Took me 2 hours to figure the damn thing out... the motor housing easily snaps out of the mirror housing. There's a T10 Torx screw in the middle that also holds the motor housing to the mirror housing, and also acts in part to hold the halves of the motor together. After removing the motor entirely, I stared at it for awhile trying to see why it wouldn't go together... it's hard to explain. Basically the half with the actual motors has a notched ring all the way around, and this ring snaps inside of the other half. Not without a ton of prying and pressing force though. I can't believe it came apart, and I REALLY can't believe I got it back together. Was about to throw it across the driveway and go to the dealer this week to hopefully get a new one, but I couldn't find the part online and the numbers on the motor housing didn't lead to anything, so I figured I needed to fix it myself.
This was the 4th mirror I did. The first 3 went smooth as butter. I should have known something was up when this mirror didn't come apart as easily/quickly, yet I kept pulling... probably needed to use more heat, but maybe it was unavoidable. I have used the suction cup tool... wouldn't try it with anything else.
Facing the same now,
its just incredible how those two parts can ever fit together again
