A common problem caused by weak adhesive or extreme heat.

If the mirror shakes while driving, the mount may be worn out.

Tools Needed to Replace a Rear View Mirror
Most rear-view mirror replacements require only a few simple tools. Common tools include:
- Screwdriver
- Rear view mirror adhesive kit
- Razor blade or scraper
- Glass cleaner
- Marker or tape
A mirror adhesive kit is especially important because regular glue usually won’t hold properly on glass.
Step-By-Step: How To Replace Rear View Mirror
Let’s go through the process in detail.
Step 1: Remove the Old Rear View Mirror
Start by removing the broken or loose mirror. Most mirrors attach in one of three ways:
- Set screw mount
- Twist-on mount
- Clip mount
Use a screwdriver to loosen the set screw if necessary. Then gently slide the mirror upward or twist it off the mounting button. Be careful not to apply too much force, especially if the windshield mount is still attached.
Step 2: Remove the Old Mounting Button
If the mirror mount is still stuck to the windshield but damaged, it needs to be removed. Use a razor blade or scraper to carefully remove the metal button and old adhesive. Take your time during this step to avoid scratching the glass.
Step 3: Clean the Windshield Surface
Proper cleaning is critical for strong adhesion. Use:
- Glass cleaner
- Rubbing alcohol
- Lint-free cloth
Make sure the surface is completely clean, dry, and free of old adhesive. Any dirt or grease can prevent the new mount from sticking.
Step 4: Attach the Mounting Button
Most replacement kits include a metal mounting button and adhesive. Apply the adhesive to the button and press it firmly against the windshield. Important tips:
- Mark the correct position before installing
- Hold the button in place for 30–60 seconds
- Allow adhesive to cure for 15–30 minutes
Some adhesives require up to 24 hours for full strength.
Step 5: Install the New Rear View Mirror
Once the mounting button is secure, attach the new mirror. Depending on the mirror type:
- Slide the mirror onto the mount
- Twist into place
- Tighten the set screw
Make sure the mirror is firmly attached.
Step 6: Adjust the Mirror Position
Finally, adjust the mirror for proper visibility. The mirror should allow you to see:
- The entire rear windshield
- Traffic behind your vehicle
- Minimal interior reflection
Correct adjustment improves driving safety and awareness.
Rear View Mirror Replacement Cost
If you prefer professional installation, here’s what you can expect to pay.
| Replacement Type | Average Cost |
| DIY Replacement | $15 – $60 |
| Mechanic Installation | $50 – $120 |

Doing it yourself can save $50 or more in labor costs.
