How to replace your mirror glass

If your wing mirror glass breaks or cracks, it’s important to fix it as soon as possible to stay safe on the roads. 

In many modern cars, the glass will come pre-fixed to a back plate, so it won’t be as easy as removing the old mirror and attaching a new one. However, this is still a job that you can tackle yourself, in a few simple steps.

In this guide, we’ll walk you through the step-by-step process to replace your car mirror glass right on your drive.

How to replace mirror glass

First, position your wing mirror glass facing inwards towards your car – this should leave a larger gap for you to work with.

Then use a trim removal tool or other plastic tool to pop the glass and back plate off, gently wiggling from side to side until it releases. To avoid damaging your paintwork while doing this, place a microfibre cloth over the wing mirror.

The back plate should still be attached via two wires – these are the heating connections. Disconnect each one, making sure to remember which one connects to each terminal. With the old glass and back plate removed, you can now fit the new unit.

First, reconnect the two wires in the correct order, then you can reattach the back plate. 

Use the fixings on the back as a guide to locate the back plate, then push until you hear it click into place. Try to press evenly across the glass to avoid any breakages.

And that’s it – your new mirror glass should be fitted and working perfectly.
