Will this work with my factory mirror housing?

Yes. This is a direct OE replacement lens — it mounts into your existing mirror housing without modification. Verify your current housing is intact before ordering.

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

Most drivers can access the lens from behind the housing without full removal. Consult your service manual for the exact procedure on your model year.

How do I activate the heating function?

The heating element works through your factory mirror controls — no additional wiring needed. Test the defrost button after installation to confirm the connection is live.
