Will this work with my factory mirror housing?

Yes — this is OE-style glass designed to fit directly into the existing mirror assembly without modification. Mounting tabs align with factory points.

Do I need to prep or paint this before installing?

No prep needed. The glass lens comes ready to install. It's not a paint-able component — the heating element sits on the back surface.

What if the heating element doesn't work after install?

Test the connection to your mirror harness first — ensure the plug is fully seated. If power reaches the glass and it still doesn't heat, contact support with your order number and photos of the connection.
