Is it Possible to Just Replace the Side Mirror Glass on a Mazda?
A broken side mirror isn’t fun to deal with. Replacing the entire mirror assembly can be costly and time-consuming.
Does your side mirror glass appear to be the only thing that’s broken? We completely understand why you’re looking to replace just that part. After all, a side mirror glass replacement is:
- Cheaper: Much cheaper, actually. For example, a replacement side mirror glass for a 2017 Mazda CX-3 (part no. KR22-69-1G1) is nearly $100 cheaper than a side mirror assembly for the same car (part no. DB2P-69-121B).
- Easier: All you have to do is to pop off the glass and then push the new one back in. This task is much easier than doing a full side mirror replacement. A full replacement involves removing the panel inside the door, unbolting all the bolts, disconnecting a wiring harness, and so on.
- Less time-consuming: It takes only 10 minutes to replace the glass. That is a heck of a lot shorter than 1-2 hours, which is how long it typically takes to replace the entire assembly.
If you can replace just the glass, then by all means go for it! However, first you need to make sure that the glass is the only component that’s broken.
How to Determine That You Can Just Replace the Glass
The way to do this is to check your side mirror assembly to make sure that nothing else is broken. A thorough check can be done in three steps:
- Visual inspection: Look over the side mirror for cracks or any other type of damage that may affect the inner workings or the mounting of the mirror. Be sure to check the underside, especially near the pivot, as well.
- Pressure test: To make sure that the mirror isn’t loose, gently rock the mirror housing in all directions (left, right, up, and down). Retighten the bolts if the housing feels loose.
- Power mirror test: Us the power mirror controls to move the mirror fully in all directions. This is to make sure that there are no wiring issues or mechanical damage.
If your side mirror passed all three tests, then you should be able to replace just the glass.
How to Replace the Glass
First, you’re going to need two things:
- A replacement side mirror glass (you can buy an OEM side mirror glass here)
- Duct or masking tape
First, cover the broken glass in duct or masking tape. This helps protect your fingers from any glass shards that may break off during removal. You may also want to wear thick gloves for the same reason. Then start replacing the mirror.
Here are the steps:
- Turn the mirror glass inwards to expose the outer part of the glass as much as possible. (This means if the broken mirror is on the right side of the car, turn the mirror glass all the way to the left. If it’s on the left side of the car, turn it all the way to the right.)
- Insert your hand behind the outer part of the glass and gently pull the glass back slowly. Try to pull from the center of the glass to avoid cracking the mirror even further.
- When you can get your fingers under the bottom side of the mirror, detach the pin located there.
- Pull the mirror back even more and then detach the pins on the left and right side of the mirror.
- Disconnect any mirror heater connectors if needed.
- Connect the mirror heater connectors to the new mirror if needed.
- Line up the mounting pins with their respective slots. Gently push the new mirror into the housing.*
*Be sure not to rush through this step. The replacement mirror and other components are fragile and you don’t want to accidentally break anything. When pushing the mirror into the housing, do it with your fingers placed in the center of the mirror, not the edges.
