Does OEM number 4M5T-14A389 fit my vehicle?

OEM number 4M5T-14A389 fits the Ford Focus II (MK2), built between 2004 and 2012, across hatchback (platform code DA, HCP, DP), saloon (DB, FCH, DH), and estate / station wagon (DA_, FFS, DS) body styles. The part is fitment-agnostic with regard to engine type and displacement — all petrol, diesel, and Flexifuel variants within the Focus II range are covered, including the high-output 2.5 ST (engine code HYDA, 166 kW / 225 hp). The part is specific to the front left (driver's side on left-hand-drive vehicles) door position; a separate OEM number applies to the front right, rear left, and rear right positions.

No KESSY, software coding suffix, or trim-level constraint has been identified as gating fitment within the Focus II generation. The part is confirmed for left-hand-drive (LHD) configurations; fitment to right-hand-drive (RHD) variants should be verified against the number printed on the existing motor, as door-mirroring may require a different part number.

OEM number 4M5T-14A389 may fit additional vehicle models not listed here. Always verify by checking the OEM number printed on your existing part or by using a VIN-based parts lookup.

Fits:    Ford Focus II (MK2) — Hatchback (2004–2012), Saloon (2005–2012), Estate (2004–2012) — front left door position — all engine codes — LHD confirmed
Does not fit: Front right, rear left, or rear right door positions (separate OEM numbers required)

Cross-reference data also associates OEM number 4M5T-14A389 with the Ford Focus III Saloon (engine code UKDB, 2.0 TDCi, 100 kW / 136 hp, 2010–2014), but the Focus III is a distinct, later platform generation — verify the printed number on your existing part before ordering.

When should OEM number 4M5T-14A389 be replaced?

Replacement triggers

• The driver's side front window fails to move when the switch is pressed, despite the fuse being intact.
• The window moves only intermittently, stopping and restarting without a consistent pattern.
• The window operates in one direction only (either up or down) but not both.
• A grinding, clicking, or whirring noise is audible from inside the front left door when the window switch is activated.
• The window moves noticeably more slowly than it previously did under normal operating temperatures.
• The window drops under its own weight when the door is closed firmly, indicating the motor can no longer hold the glass position.

Typical lifespan

The front left window motor typically lasts between 10 and 15 years or 150,000 to 250,000 km under normal usage. Lifespan is shortened by frequent use in cold climates, where increased resistance in the regulator mechanism places higher current demand on the motor windings, and by water ingress into the door cavity caused by degraded door seals.

Replacement interval

There is no scheduled replacement interval for the front left window motor. The part should be replaced on confirmed failure or on the appearance of any of the symptoms listed above.
