* Type of mirror: Is it a manually adjusted mirror or power-adjusted? Power mirrors are slightly more complex due to the wiring.
* Condition of the mirror: If the old mirror is heavily rusted or stuck, removal might be more challenging.
* Your mechanical aptitude: If you're comfortable with basic hand tools and have some experience with car repairs, it should be straightforward.
What to expect:
* Removal: Usually involves removing a few screws or clips holding the mirror housing to the door. You might need a trim tool to avoid scratching the paint.
* Wiring (power mirrors): If it's a power mirror, you'll need to carefully disconnect the electrical connector. Take a picture beforehand to ensure proper reconnection.
* Installation: The new mirror should simply attach in the reverse order of removal.
Tools you'll likely need:
* Screwdrivers (Phillips and possibly flathead)
* Trim removal tool (plastic pry tool is ideal to prevent scratching)
* Possibly a socket wrench (depending on the mounting screws)
* Electrical connector disconnect tool (if applicable, but you can often disconnect by hand carefully)
Overall: You can likely find a detailed video tutorial on YouTube for your specific Lumina model. If you're unsure about any step, watching a video before starting will significantly improve your success. It's a job most DIYers can handle, but if you're completely uncomfortable working on your car, taking it to a mechanic is always an option.
