Does this require any wiring work, or does it plug into the existing mirror harness?

The heating element connects to your factory mirror wiring — no new circuits or relays needed. Confirm your vehicle's mirror connector matches before installation.

Will this work if my current mirror glass is cracked or fogged?

Yes. This is a direct swap for damaged or deteriorated glass. Remove the old glass from the mirror housing and install this assembly using the same mounting tabs or clips.

What's the return window if the glass doesn't fit or the heater doesn't work?

Check our return policy on modsupply.com — standard coverage applies. Test fit before final installation to confirm proper seating in your mirror frame.
