Will this connect to my car's existing mirror controls?

Yes—this assembly mounts at factory points and integrates with your stock electrical harness. Power and ground connections use OEM connectors, so it plugs directly into your vehicle's wiring without modification.

Does the heating element work independently or only when the defroster is on?

The heating element operates through your vehicle's climate control system. Activation depends on your model's wiring—some vehicles run heat only when the rear defroster is activated, others have independent mirror heat switches. Check your owner's manual to confirm your setup.

What if the mirror glass is damaged after arrival?

Inspect the unit immediately upon delivery. If glass arrived cracked or delaminated, document it with photos and contact support with your order number for evaluation. Undamaged assemblies ship secure, but damage claims need photographic evidence within 7 days of delivery.
