Cheap Fiat Fullback Window Regulator

The Fiat Fullback ran from 2016 to 2020, based on the L200 fourth generation platform, and received a mild facelift around 2018 that was largely cosmetic. For window regulators the key factors are the door position (NS or OS) and whether you have a front or rear door, not the facelift year itself. That said, confirm with your breaker against your registration before buying, as subtle running changes can affect regulator mounting points across the 2018 boundary.

The 2018 facelift is a known production boundary for the Fullback, and while the door structure did not fundamentally change, whether the regulator mechanism interchanges across that year is something you should confirm with the breaker against your exact registration. Quote both the donor year and your registration so they can cross-reference. Never assume a pre-2018 unit is a guaranteed drop-in for a post-2018 vehicle.

Trim level alone does not affect window regulator fitment on the Fullback; the regulator is determined by the door position (NS offside driver's side, or OS nearside passenger's side) and front versus rear. Cross, LX and SX share the same door shell on equivalent model years, so you do not need to match trim. Be aware that higher trims may have electric regulators with slightly different motor brackets, so confirm electric versus manual compatibility with your breaker if you are unsure which type your vehicle has.

No — NS (nearside, passenger left) and OS (offside, driver right) front regulators are mirror-image units and are not interchangeable. Always specify clearly which side you need when contacting a breaker, as fitting the wrong side will mean the mechanism runs in the wrong direction and the part will not work. Double-check your side before ordering to avoid unnecessary returns.

Front and rear door regulators are different parts on the Fullback — the door aperture sizes and mounting positions differ — so a front regulator cannot simply substitute for a rear one or vice versa. When contacting a breaker, specify front or rear as well as NS or OS to make sure you get the correct unit. Providing your registration gives the breaker the best chance of matching the right part.

Engine type has no bearing on window regulator fitment whatsoever — a 2.4 diesel donor car supplies the same regulator as any other engine variant in the same model year and door position. Colour of the donor vehicle is also irrelevant, as the regulator is a mechanical frame component and not a painted surface. Focus instead on year, NS or OS side, and front or rear door position when speaking to your breaker.
