There's a reason so many people end up driving around with a cracked wing mirror for weeks - they assume it's a garage job. It isn't. On modern cars, the mirror glass clips directly onto the motor housing inside the casing. Pull one off, push another on. The whole thing takes less time than parking.
This guide explains what you need, how the fitting works, and how to pick the right glass for your car.
What you'll need
- Replacement clip-on wing mirror glass - matched to your make, model, year and side
- Your hands
Seriously, no tools. The glass locks onto the motor housing with a clip plate - the same way the original was fitted at the factory. There's nothing to unscrew, no adhesive to apply, no trim panels to remove.
How to fit it - step by step
Step 1 - Get the right glass before you start
The clip plate on the back of the glass is shaped to match your specific motor housing, so vehicle matching matters. You need to know your car's make, model, year, and which side you're replacing - driver's or passenger's.
You also need to check whether your mirror is heated. Look at the glass from outside - if there's a faint wire element visible, it's heated. Both heated and non-heated versions clip on the same way, but heated glass has two small connector pins at the back that need plugging in before you clip it in.
Browse by make and model in the wing mirrors collection.
Step 2 - Remove the old glass
Fold the mirror housing in towards the car first - it gives you a better grip and takes some tension off the casing.
Grip the glass firmly with both hands and pull it straight back from the housing with a short, sharp tug. It'll feel solid, but the clip is designed to release with a bit of force. You won't damage anything.
If the old glass is already broken, wrap it in a cloth before gripping so you're not pulling on sharp edges.
On heated mirrors, once the glass comes loose you'll see two small electrical connectors at the back. Unplug those before putting the old glass aside.
Step 3 - Connect the heater cables (heated mirrors only)
Before clipping the new glass in, connect the two heater pins on the back of the new plate to the connectors on the motor housing. Push each one until it seats properly. Do this now while you can still see what you're doing - once the glass is clipped in there's no access to the back.
Non-heated mirror? Skip to step 4.
Step 4 - Clip the new glass in
Hold the new glass up to the housing and feel the clip plate locate against it. It'll only align one way - if it doesn't sit naturally, rotate 180 degrees and try again.
Once it's lined up, press firmly with both thumbs until you hear and feel the clip lock in. Give it a tug to confirm it's solid. Unfold the mirror, adjust the angle, and that's it.
Convex or wide angle - which one do you need?
This is worth getting right before you order, because the two types give you a different view.
Convex glass has a gentle outward curve. It's the standard type for the passenger side on most UK cars - the curve gives a wider field of view than a completely flat glass, while keeping the image fairly natural.
Wide angle glass (also called aspheric) has a more pronounced curve, especially towards the outer edge. You'll find it on the driver's side on most modern UK cars - the sharper angle gives better coverage of the blind spot directly alongside the car.
The rule: replace like-for-like. Driver's side usually takes wide angle, passenger's side usually takes convex. If you're not sure what you had, the product listings on the site are filtered by side and type for each vehicle - so if you select driver's side for your car, you'll see the right option.
What if the housing is cracked too?
If the plastic casing around the mirror took damage as well - a car park knock, a snapped cap - the mirror covers collection has replacement housings sorted by make and model. Worth doing both at the same time if the housing is visibly cracked, since you've already got the mirror folded in.
Common questions
How long does it actually take?
Two minutes for a non-heated mirror. Around five if you're connecting heater cables for the first time. That's not marketing - once the right glass is in your hands, the fitting itself is genuinely that quick.
Do I need to connect the heater cables for the mirror to work?
No - the mirror functions as a mirror either way. The heater cables only power the heating element that clears condensation and ice. If you don't connect them the glass still clips in and works perfectly, you just won't have the heated function. Worth connecting if you're already doing the job, but it's not essential.
Will the clip definitely fit my car?
If you select by make, model and year it will. The clip plate is specific to each vehicle - it's shaped to sit flush on that exact motor housing. A glass listed for a Focus Mk3 won't clip onto a Mk2 housing. The vehicle selector on the product page handles this, so as long as you enter your car correctly you'll get the right fit.
The old glass is smashed and I can't get a grip on it - what do I do?
Wrap it in a cloth or plastic bag before you grip it. This holds the pieces together and protects your hands. The clip releases the same way - firm pull straight back. Once it's off, bag it up for disposal.
Can I drive with a broken or missing wing mirror glass?
UK law requires a minimum of two working mirrors. If the passenger side is the only one affected and your interior mirror is intact, you're technically within the rules for a short journey. But a missing mirror is an MOT failure, and the blind spot it creates is a real risk. It's a two-minute job - worth doing before you next drive rather than after.
