1. Assess the Damage:
* Mirror Arm: Is it simply bent, or is it fractured? A slight bend might be correctable with careful manipulation and possibly some heat (carefully apply heat with a hairdryer – avoid direct flame). A fracture will likely require replacement.
* Wiring: This is crucial. Inspect the wires carefully. Are they just disconnected, frayed, or broken? Trace the wires back to the connector to determine the extent of the damage. Photograph everything before you do anything else!
2. Options:
* Replacement (Recommended): The easiest and most reliable solution. You'll need to find a replacement mirror assembly for your Infiniti Q45 model year. You can find these through:
* Infiniti Dealers: Most expensive but guaranteed fit.
* Online Parts Retailers: More affordable options, but double-check compatibility (year, model, trim level). Websites like eBay, Amazon, and parts suppliers specializing in Infiniti vehicles are good places to start.
* Junkyards: The cheapest option, but the quality and condition of the used mirror are unknown.
* Repair (More Challenging): If only the arm is slightly bent and the wiring is intact or easily repairable, you *might* be able to fix it:
* Mirror Arm: If bent, carefully try to straighten it. Use gentle force and possibly a hairdryer to slightly warm the plastic (to make it more pliable, but be extremely cautious not to melt it). If broken, you'll likely need a replacement arm (if you can find one separately).
* Wiring: If the wires are just disconnected, carefully reconnect them. If they are frayed or broken, you'll need to solder them. Use heat-shrink tubing to insulate the repaired connections. If the damage is extensive, replacing the entire wiring harness may be necessary (a difficult task).
3. Removal and Installation (Applies to both replacement and repair):
* Consult a Repair Manual: A repair manual specific to your Infiniti Q45 model year will be invaluable. It will show you exactly how to remove the door panel, disconnect the mirror, and reinstall everything. You can find these online (Haynes, Chilton) or through your local auto parts store.
* Door Panel Removal: This usually involves removing screws, clips, and possibly some trim pieces. Be gentle to avoid damaging the panel.
* Mirror Connector: Once the door panel is removed, disconnect the electrical connector from the mirror.
* Mirror Removal/Installation: Carefully remove or install the mirror according to the instructions in your repair manual.
4. Testing:
* Once the mirror is reinstalled, connect the battery and test the mirror's functionality. Make sure all adjustments (up/down, left/right) are working correctly.
Important Considerations:
* Safety First: Disconnect the negative battery terminal before working on the electrical system.
* Patience: This is a somewhat delicate process. Take your time and be careful not to damage anything further.
* Professional Help: If you're not comfortable working on your car's electrical system or you're unsure about any step, it's best to take your vehicle to a qualified mechanic or auto body shop.
Replacing the entire mirror assembly is usually the simpler and more reliable solution, especially if the wiring is damaged. Repair is only viable if the damage is minimal and you have the necessary skills and tools. Remember to always prioritize safety.
