Will this mirror plug directly into my existing wiring harness?

Yes. This is the factory assembly, so all connectors and pin layouts match the original wiring on your Pathfinder. No adapter or rewiring needed.

Does the heater element work independently, or does it activate with the defrost button?

The heater is integrated into the assembly and operates with your vehicle's climate controls. Refer to your owner's manual for heater operation specifics.

What if the mirror glass is damaged during shipping—what's the return process?

Inspect the mirror immediately upon delivery. Damage claims must be reported within 7 days of receipt with photos. Contact support with your order number and images for next steps.
