I have to repair/replace the right side door mirror on an '06. The mirror glass and light lens are both broken, but the rest of the unit is fine. I have a recycled mirror, complete except for incorrect color. My first choice is to swap out the mirror glass and lens, if possible. Alternatively, I'll have to paint the replacement and swap out the entire unit. When the mirror is swung out against the spring tension, the mounting screws appear to be visible. They actually look like security screws so I'll have to invent a tool to remove them. How do I release the spring tension so the mirror will stay swung out of the way while I take out the screws? Once I get it off, will I be able to cannibalize the mirror and lens or must I paint and replace the whole thing?
