Toyota Yaris Wing Mirror: Specs, Fitment & Common Faults

On the Yaris, the toggle switch has three distinct positions, and the middle one is specifically required for auto-fold-on-lock.

A Genuinely Useful Explanation Worth Knowing About the Toggle Switch

If auto-folding on locking has stopped working but the mirrors still fold manually, this is genuinely worth understanding: the mirror control toggle switch commonly has three distinct positions. Fully out in one direction keeps the mirrors extended permanently. The middle, neutral position is specifically what enables auto-fold when the car is locked. Fully in the other direction keeps the mirrors folded permanently. Many owners genuinely don't realise this middle position is required specifically for auto-fold to work at all.

A genuinely useful diagnostic distinction worth knowing: if the mirrors fold correctly when pressed manually, but don't fold automatically when locking, this points toward the locking signal or its wiring specifically, rather than the mirror's motor.

It's also worth knowing that if only one side has stopped folding while the other works perfectly, this points toward a fault isolated to that specific side rather than anything affecting the shared locking system.

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 Yaris. 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 Yaris 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.

Fitment & Compatibility

Mirror specification differs substantially by trim level on the Yaris — a basic manual mirror and a heated, power-folding, sensor-equipped version are not interchangeable even though they may look similar from a distance. Always confirm the exact specification fitted to your specific trim before ordering, ideally by referencing your VIN rather than assuming based on the visible features. Whether you're sourcing a replacement wing mirror for your Toyota Yaris from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.

Common Faults

Symptoms Worth Knowing

Mirror won't fold or unfold — usually a failing fold motor rather than a wiring fault, though worth checking the fuse first.
Indicator repeater not working — often a simple bulb or LED failure, though integrated units may require replacing the whole mirror glass assembly.
Heating element not clearing condensation — can indicate a failed heating element or a blown fuse specific to that circuit.
Cracked or shattered housing — usually impact damage, and a straightforward like-for-like replacement in most cases.

DIY Replacement Difficulty

Replacing the mirror glass alone is usually an easy DIY job on most versions. Replacing the entire mirror housing is more involved, typically requiring removal of an interior door panel trim piece to access the wiring connector, and blind-spot sensor-equipped mirrors may need recalibration afterward. Expect 15–30 minutes for a glass-only swap, or up to an hour for a full housing replacement.

OEM vs. Aftermarket

For basic, non-electronic mirrors, reputable aftermarket parts are a perfectly reliable, cheaper alternative to OEM. For mirrors integrating blind-spot sensors or advanced electronics, OEM parts are strongly recommended given the calibration and compatibility risks involved with aftermarket sensor-equipped units.
