Will this plug straight into my car's existing wiring?

Yes. This mirror uses factory electrical connectors designed for your vehicle's harness. Plug the assembly into the existing connector under the dash or door panel — no rewiring needed.

Does the heating element work independently, or do I activate it the same way as the defroster?

The mirror heating typically ties into the factory climate controls or a dedicated button on the mirror switch panel. Your existing controls will command it once installed — no additional switches required.

What if the power fold isn't working after I install it?

Check your factory connector for corrosion or a loose pin before assuming the mirror is faulty. If the connector is clean and tight and the motor still won't engage, the assembly may have a defect — contact support for return authorization.
