How to Replace the Rearview Mirror Assembly?
4 Answers
First, use a wrench to pry off the surface casing of the damaged rearview mirror. Insert your hand behind the glass and pull outward to remove the mirror. Then, unscrew the four screws to detach the frame and rear casing. Prepare the new rearview mirror, align it with the screw holes, and tighten the screws.
Last time I replaced the side mirror myself, I remember it involved these steps: First, remove the door trim panel by carefully prying open the clips with a plastic pry tool to expose the screw holes inside the door panel. Then locate the three screws securing the side mirror and loosen them one by one with a Phillips screwdriver—remember to support the mirror housing with your hand to prevent it from suddenly falling. Next, disconnect the wiring harness; some connectors for heated mirrors or turn signals have clip-style fasteners that can be released with a press of your fingernail. When installing the new assembly, first align the screw holes, tighten them about 80%, then reconnect the wiring harness. Finally, test the turn signals and power adjustment functions before fully tightening everything. It’s best to wear gloves throughout to avoid scratching the paint. After installing the new mirror, remember to adjust its angle before driving. The whole process takes about half an hour.
Replacing the side mirror assembly requires proper tools and the right mindset. The toolkit should include a Phillips screwdriver, plastic pry tools, and a towel. Before starting, disconnect the vehicle's power to avoid short circuits. Patience is key during the operation—older car clips are brittle and prone to breaking, so it's advisable to take photos of screw positions as you disassemble. I've found that most models hide the mirror base behind the triangular plastic cover in the door panel; when removing the cover, apply angled force rather than brute strength. Wiring connectors often have waterproof sleeves—applying a bit of petroleum jelly makes separation easier. When installing the new assembly, repeatedly check for the audible click of connectors seating properly. Hand-tighten screws first before using tools for final torque, and don't forget to reattach the door seal. For vehicles with mirror memory function, it's best to visit a professional shop for ECU programming.
For beginners, it's recommended to have it replaced at a repair shop, as it involves wiring safety. If you choose to do it yourself, first look up tutorials for your specific car model online. When purchasing parts, opt for assemblies with original factory codes, as aftermarket parts may have color discrepancies. Wear an anti-static wristband during the operation, and start prying the interior trim from beside the door storage compartment, avoiding metal tools. Pay special attention to the positive and negative terminals of the electrical connectors, and label them with tags before disassembly. Testing is crucial: check the tilt-down function in reverse gear, test the heating and defogging by spraying water, and ensure the turn signal flashes three times normally for a successful installation. After completion, press the door interior trim to check for any unusual noises, and avoid washing the car for three days to prevent moisture intrusion.
