Here is the process used to remove the side mirrors on the Scion iQ.

Tools required...
Philips screw driver, assorted interior removal tools



Remove this small triangular piece from the front edge of the door, easy to pull off with your hands...





Remove the door latch backing plate by prying the trailing edge with a plastic pry tool...







Remove the retaining screw from the exposed door latch area...



Use a small pry tool to lift the circular cover located inside the arm rest grab handle...



Remove the now exposed screw from the grab handle...



Using a plastic pry tool remove the arm rest cover plate. This piece is tough to pull off but it has nothing holding it other than plastic tabs...





Remove the two screws behind the arm rest panel...



The door panel can be removed without this next step but I find it easier to manage holding the door panel with the window switch disconnected. Lift the window switch body from the door panel...



Disconnect the wire loom plug from the window switch...



Disconnect the wire loom plug from the dome tweeter speakers...



Grab the door panel at the lowest corner and pull, the small plastic tabs that hold the panel on will pop loose for you. Work your way around the door...







Remove the door latch from the door panel by sliding the plastic tabs from their mounting holes...





The door with the panel removed...



Grasp the mirror panel firmly and pull up. It will take some force to remove the panel from the clips behind it. Keep even steady pressure on the mirror panel until it pulls clear of the clips...



The inside of the mirror housing...



Remove the retaining screws with a Philips screw driver...





The front cover may now be removed from the mirror housing...





Remove the wire loom connector from the mirror housing...



The stock turn signal lamps are removed using a Philips screw driver...







If you wish to remove the entire mirror housing from the vehicle use a 10mm socket on the three inside bolts...



Remove the small plastic pin that holds the weather stripping on the door...





Disconnect the wire loom connector from the plug...





Your mirror housing is now removed from the door...
