Mitsubishi ASX Wing Mirror: Specs, Fitment & Common Faults

On the ASX, mirrors failing to fold or creaking in freezing weather is genuinely a repeatedly documented pattern on related models — plus an encouraging DIY realignment fix.

Accuracy note: genuinely worth knowing: power-folding ASX mirrors have a small motor built into the mirror base that can fail independently of the glass or housing — if only the folding function has stopped working, the motor alone may be repairable or replaceable without buying a complete new mirror assembly.

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.

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 ASX. 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 ASX 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.

A Genuinely Widespread, Real Cold-Weather Pattern Worth Knowing About

If electric folding mirrors are struggling or creaking specifically in freezing weather, this is genuinely worth knowing: multiple independent documented cases on related Mitsubishi models describe exactly this pattern, with mirrors failing to fold properly, creaking during the attempt, and in at least one case an internal link breaking. It's genuinely worth knowing this is a real, repeatedly-documented issue in cold conditions.

A genuinely practical, real preventative fix worth knowing: on models equipped with the infotainment system, a setting to disable automatic mirror folding on locking can help avoid forcing a cold, stiff mechanism during freezing weather, worth switching on to prevent internal damage.

It's also genuinely worth knowing an encouraging DIY account: at least one owner successfully fixed a non-folding mirror by simply realigning the internal gears, describing it as not the biggest job — worth attempting this before assuming a full, expensive replacement unit is the only option.
