Second Hand Hyundai i40 Window Winder Motor

The Hyundai i40 was sold in the UK as a single generation, running from 2011 to 2019, with a facelift introduced in 2015. Within the pre-facelift (2011–2015) and post-facelift (2015–2019) periods parts are generally consistent, but whether a motor from one side of the 2015 facelift boundary will swap straight into the other is something you should confirm with the breaker against your registration, as trim and door-frame details can vary across a refresh. Always quote your reg so the breaker can check the exact specification.

Yes, it matters — window winder motors are side-specific because the regulator mechanism is handed, so a nearside (NS, passenger/left) unit will not correctly fit an offside (OS, driver/right) door and vice versa. When asking for a quote on Findapart, always specify NS or OS clearly so the breaker pulls the correct part. Fitting the wrong side is a common and easily avoided mistake.

For the front doors, the saloon and estate (Tourer) share the same door structure, so the window winder motor should be the same for front NS or OS positions regardless of body style. Rear doors differ in size and frame between the saloon and estate, so for a rear motor you must tell the breaker both the body style and which door you need. Quote your reg to be certain the breaker is matching the right configuration.

Trim level — Classic, Active, Style, Premium, or Sport — does not affect the fitment of the window winder motor itself; the door frame and regulator are the same across the range. You may find cosmetic differences such as door-card finish or speaker placement on the donor car, but the motor is a mechanical component that fits independently of those. Confirm the side, door position, and body style with the breaker and you should be fine.

The 2013 car is pre-facelift and the 2017 is post-facelift, with the i40 receiving its facelift in 2015, so these sit on opposite sides of that boundary. The parts may well interchange, but because detail changes can occur at a facelift you should not assume compatibility and instead confirm directly with the breaker, quoting both registrations. A good breaker will cross-reference part numbers to give you a definitive answer before you commit.

Breakers often remove and sell the motor and regulator together as an assembly, since separating them adds labour and the pair is usually sold as one unit from dismantled cars. It is worth asking the breaker specifically whether they can supply the motor alone, but be prepared that a full regulator-and-motor assembly may be what is available and can still be the most practical solution. Either way, confirm the side (NS or OS) and door position when you request your quote.
