How to Replace a Rearview Mirror in a Corolla
Introduction
In most vehicles, the rear-view mirror is bonded to the windshield by special glue that can support the heaviness of the mirror. Eventually, the glue dries and weakens and the mirror no longer sticks to the windshield. Replacing a rear-view mirror is not difficult or time-consuming. You will spend most of your time waiting for the glue to dry enough that you can drive your care safely again. Check the owner’s manual of your Corolla for further instructions.
Difficulty: Moderately Easy
Things You'll Need:
- Allen wrench
- Razor or putty knife
- Alcohol
- Activator
- Glue
- New rear-view mirror
Instructions
Step 1
Detach wiring that may be attached to the rear-view mirror by pulling tabs away from the harness. Use an Allen wrench to loosen the screw on the rear-view mirror. Slide the mirror off.
Step 2
Locate the metal button that will be attached to the windshield. Trace the place that the button is with a writing utensil. This mark will tell you where to install your new mirror.
Step 3
Scratch the button off slowly using a razor or a putty knife to scrape away the glue holding the button in place. Do not use too much pressure or the windshield will crack. Make sure the area where the button was sitting is smooth.
Step 4
Clean the area where the button was with alcohol. Use alcohol to clean the button too. Wait five minutes for the button to dry.
Step 5
Break open the vial of activator. This will cause the cotton in the vial to fill up with fluid. Put activator on the button. Squeeze out one drop of glue and let it fall onto the button. This will cause the activator and the glue to mix.
Step 6
Hold the button onto the windshield, glue side down, for around 60 seconds. The button needs to sit for over an hour. This is necessary in order to make sure that the button bonds to the glass properly.
Step 7
Attach the new rear-view mirror onto the button by sliding the back of the mirror onto the button. Secure the mirror by tightening the Allen screw and fiddle with the mirror until you are happy with its position. Reattach any wires that you disconnected.
Tip
If the button is not securely attached after waiting an hour, remove the mirror and wait another hour for the glue and activator mixture to dry properly.
