Can I replace my rear view mirror myself?
Yes. In many cases you can replace a rear-view mirror yourself, including both interior and exterior mirrors, as long as you have the correct replacement part and mounting method. If your car uses advanced safety features or sensors near the mirror, professional recalibration may be required after replacement.
This guide explains when DIY is feasible, what tools you’ll need, and a step-by-step process to replace common rear-view mirrors while keeping safety in mind. It also notes high-tech considerations for ADAS-equipped vehicles.
Understanding what you’re replacing
Interior rear-view mirror
The interior rear-view mirror is usually mounted to the windshield or a small base at the top center. Some are clip-on, some screw to a base, and newer models may include auto-dimming or electronic features. If the mirror contains sensors or electronics, follow the manufacturer’s instructions. Vehicles with ADAS cameras near the mirror may require recalibration after replacement.
Exterior side mirrors
Exterior mirrors are mounted on the door and typically involve removing interior trim, disconnecting wiring, and reseating a replacement housing. If your mirrors include heating elements, integrated turn signals, or auto-dimming, you’ll need to transfer or reconnect those components carefully. Exterior mirror replacement is generally more involved than interior mirror replacement.
What you’ll need
The following list covers common tools and parts for DIY rear-view mirror replacement. Your exact setup may vary by make and model.
- Replacement mirror or replacement mounting kit compatible with your vehicle
- Adhesive and applicator (for windshield-mounted bases) or mounting screws/bolts (for screw-on or clip-on bases)
- Basic hand tools (screwdrivers, metric/SAE wrenches or a small socket set)
- Trim removal tool or flat-head screwdriver to release interior panels (for exterior mirror replacement)
- Cleaning supplies (isopropyl alcohol, glass cleaner, microfiber cloth)
- Masking tape and protective coverings to protect the windshield and interior
- Optional: line (fishing line or dental floss) to help separate old adhesive
- Safety gear: gloves and eye protection
Note: If your replacement uses windshield adhesive mounting, ensure you have the correct kit and follow curing times exactly. For ADAS-equipped vehicles, confirm whether recalibration is needed after installation.
Before attempting the replacement, gather the right parts for your specific model and review any vehicle-specific instructions from the manufacturer or a trusted parts retailer.
Step-by-step DIY replacement (interior windshield-mounted mirror)
The following steps describe a typical DIY process for replacing an interior windshield-mounted rear-view mirror. If you have an exterior mirror or a non-standard mounting, adjust accordingly and refer to your vehicle’s manual.
- Identify the mounting type on your current mirror (clip-on, screw-on, or windshield-adhesive base) and verify compatibility with the replacement part.
- Detach the old mirror: for clip-on or screw-on bases, remove the mounting screw or unclip the mirror from its base. If the base is glued to the windshield, gently slice the old adhesive with a line while applying light heat to soften it, being careful not to crack the glass.
- Clean the mounting area: wipe away old adhesive residue and any grime from the windshield surface to ensure a clean bonding area or base seating.
- Install the new base: apply the replacement adhesive pad or attach the new base to the windshield or door frame per the manufacturer’s instructions. If using epoxy or a curing adhesive, allow the recommended cure time before proceeding.
- Attach the mirror: connect the mirror body to the new base or secure it to the door using the provided screws or clips. Tighten firmly, but avoid overtightening which could damage the housing or glass.
- Align and test: sit in the driver’s seat and adjust the mirror to ensure a clean, unobstructed view of the rear window. If the mirror has electrical features (dim, auto-dimming, or heating), reconnect wiring and verify function.
- Check for calibration needs: if your vehicle uses ADAS sensors near the mirror, confirm whether recalibration is required and arrange service if necessary.
After completing the steps, take a quick test drive to ensure the mirror stays firmly in place and provides the intended field of view. If you notice misalignment, re-tighten or re-seat as needed.
Safety considerations and ADAS cautions
Modern cars with auto-dimming, heated, or camera-based mirrors can rely on sensors near the mirror for ADAS features. Replacing these mirrors may necessitate recalibration of systems such as automatic emergency braking, lane-keeping assistance, or adaptive cruise control. If you’re unsure about the process or your vehicle’s sensors, consult the dealer or a certified technician to avoid compromising safety features. Also, work calmly and avoid damaging the windshield, especially if you’re dealing with a glue-on mount.
What to expect in terms of time and cost
DIY replacement for an interior mirror can take 30 minutes to 2 hours depending on your experience and the mounting type. Exterior mirror replacement often takes longer (1–2 hours) due to wiring and door-panel work. Costs vary by vehicle and features: basic interior mirrors may be $20–$60, while heated, auto-dimming, or signal-equipped exterior mirrors can be $50–$300+ plus labor if you hire a professional. Professional installation can ensure proper alignment and, if needed, ADAS recalibration.
Summary
Replacing a rear-view mirror is a doable DIY task for many drivers, especially with older, simpler mirrors. Ensure you have the correct part and mounting method for your model, follow the manufacturer’s instructions, and be mindful of any ADAS calibration needs on newer vehicles. When in doubt—particularly with high-tech mirrors or a damaged windshield—consult a professional to safeguard safety and accuracy.
