Will this plug directly into my vehicle's electrical system?

Yes—this uses factory connectors designed for your Cherokee's OEM wiring harness. No adapter or splicing required, just a direct connection to the existing mirror switch.

Does the heating element work independently or only when the engine runs?

Heating operates through the vehicle's electrical system and respects your factory mirror controls. Refer to your owner's manual for heating element operation and any climate-dependent behavior.

What condition is this mirror in?

Unit ships as OEM replacement stock. Verify fitment to your specific vehicle year and power mirror configuration before installation, since some base models may not have heated mirror wiring available.
