Ford Focus Mk3 Wing Mirror: Specs, Fitment & Common Faults

The well-known power-fold clicking fault has a genuinely understood mechanical cause — not a mystery, and not unique to your car.

Generation covered: this guide is for the third-generation Focus, built 2011–2018 (commonly the 2014–2018 registered examples still in daily use). The newer Mk4 Focus (2018–) uses different part numbers throughout — check your V5C logbook or VIN if you're unsure which generation you have.

The Famous "Click-Click" Powerfold Fault Has a Genuine, Understood Cause

If your power-folding mirror produces a repeating clicking noise when locking the car rather than folding smoothly, this is a genuinely well-documented Ford fault with a properly understood mechanical cause. Ford's power-fold mirrors use a simple timed relay with no current-sensing or motor-stall detection, meaning the motor keeps trying to wind the mirror inward for a couple of seconds even after it's already folded fully and physically stopped. Over time, the motor grinding against the mirror's internal case cog while stalled gradually deforms the cog's teeth, until the worm gear eventually skips past the damage entirely — producing the characteristic repeating click. One experienced owner who investigated this in detail described it as an inherent design characteristic that will eventually affect these mirrors given enough use, rather than a one-off manufacturing fault.

What this means for repair costs: once the cog teeth are damaged, replacing the mirror unit is generally the only fix — budget roughly £120 for the mirror plus around £50 labour, based on real owner quotes. Some confident DIYers have successfully repaired the internal mechanism themselves by disassembling the casing and addressing the worn cog directly, avoiding a full replacement.

More Electronics Hiding Inside Than Most People Realise

A wing mirror looks like a simple piece of glass and plastic from the outside, but on most modern cars it houses folding motors, heating elements, indicator lights, and sometimes blind-spot sensors — meaning a "faulty mirror" can mean several genuinely different things.

Before you buy: mirror specification varies significantly by trim — heated, power-folding, indicator-integrated and blind-spot-sensor versions are not interchangeable. Always confirm against your VIN before ordering.

Accuracy note: wing mirror part numbers vary by an unusually large number of factors on this car — generation, heated vs non-heated glass, folding vs manual, and whether an indicator or puddle light is built in. Confirm every one of these against your existing mirror before ordering.

Pre-facelift (2011–2015)	Different reference range — confirm generation before ordering

This is one of the more variation-prone parts on the Mk3 Focus — heated glass, power-folding, indicator repeaters and puddle lights can each be present or absent independently of each other, multiplying the number of distinct part numbers for what looks like the same physical mirror. Check your existing mirror's features carefully, or supply your VIN to a parts specialist, rather than ordering based on generation alone.

Driver's Side or Passenger Side? Sorting Out the Terminology

Wing mirrors are sold by side, and UK retailers, workshops and part catalogues don't always use the same terms for the same side — so it's worth being clear before you order. In right-hand-drive UK cars:

Driver's side = right-hand (RH) = offside (OS) — the side closest to the centre of the road.
Passenger side = left-hand (LH) = nearside (NS) — the side closest to the kerb.

Part listings may use any of these terms interchangeably — "RH mirror," "offside mirror," and "driver's side mirror" all refer to the same physical part on a UK-spec Focus Mk3. Double-check which convention your supplier is using before ordering, since a mix-up here is one of the most common reasons the wrong mirror turns up.

What It Does

Beyond the obvious job of rear visibility, modern wing mirrors on higher trims of the Focus Mk3 often integrate turn signal repeaters, puddle lights, heating elements to clear condensation, and power-fold motors for tight parking spaces. Higher-spec versions may also house blind-spot monitoring sensors, making them considerably more expensive to replace than a basic mirror.

Generations, Derivatives, Colour & Mirror Adjustment

Accuracy note: mirror covers colour-match the body — see notes below. Manual vs. electric adjustment and heated glass are general patterns by trim and era, not a substitute for confirming your exact derivative via VIN, since even within one generation the base specification can differ from what's typical for that era. This applies equally to the driver's side and passenger side mirror, which always match in adjustment type and heating.

Mk3 (2011–2018), standard trims	Colour-coded to body — common shades included Frozen White, Panther Black, Moondust Silver, Race Red; electric adjustment is standard on most trims from this generation, with heated glass increasingly common too — though the most basic specification may still be manual; confirm your exact trim
Mk3 ST (2012–2018)	Colour-coded to body — Tangerine Scream and Performance/Spirit Blue were popular ST-exclusive shades alongside Frozen White and Race Red; electric adjustment and heated glass are standard on this trim
Mk3 RS (2016–2018)	Colour-coded to body — Nitrous Blue, a unique 4-coat metallic developed specifically for the RS, was worn by over half of all UK cars; also offered in Stealth Grey (no-cost), Frozen White, Magnetic Grey and Shadow Black; electric adjustment and heated glass are standard on this trim
Mk4 (2018–present), standard trims	Colour-coded to body — common shades included Frozen White, Magnetic Grey, Agate Black; electric adjustment is standard on most trims from this generation, with heated glass increasingly common too — though the most basic specification may still be manual; confirm your exact trim
Mk4 ST-Line (2018–present)	electric adjustment and heated glass are standard on this trim
