Do I need to remove the entire mirror assembly to swap the glass?

No. The lens clips into the existing mirror housing—you can replace just the glass without pulling the whole mirror off the door. Pry the old lens out gently and snap the new one in place at the factory mounting points.

What if the mirror housing itself is cracked or broken?

This is the glass lens only. If your mirror body, bracket, or housing is damaged, you'll need the full mirror assembly instead. This works as a repair for cloudy, chipped, or scratched glass on an otherwise solid mirror.

Is there a return window if the fit isn't right?

Confirm your mirror housing is in good condition and undamaged before installation. Once the lens is seated, returns are subject to standard restocking. Test-fit first if you're unsure about mirror condition.
