Will this work with my factory mirror housing and electronics?

Yes — this is direct OEM replacement glass designed to integrate with your existing mirror assembly and heating harness. No electrical rewiring required.

Do I need special tools to swap out the old glass?

Mirror glass removal typically requires careful prying to separate the old lens from the housing backing. A heat gun softens adhesive if your unit is glued in. Check your service manual for the exact procedure for your mirror type.

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

Verify the mirror heating switch activates on your dash and confirm the connector clicked fully into place on the new lens. If power reaches the assembly and heating still fails, the issue is likely upstream in the vehicle's mirror circuit — test with a multimeter or contact a shop.
