Used Nissan 370Z Window Regulator

The Nissan 370Z (Z34) ran as a single generation from 2009 through to around 2020 with no full body-style change, so regulators from across that production run are generally considered the same platform. That said, you must also match the side — NS (nearside, passenger) or OS (offside, driver) — as the two are not interchangeable. Confirm the exact part number with the breaker against your registration before buying, as minor running changes can occur within a long production run.

Yes, it absolutely matters — NS (nearside, left/passenger) and OS (offside, right/driver) regulators are mirror-image components and will not fit each other's door. When contacting a breaker, always state clearly whether you need NS or OS. Getting this wrong is the most common fitment mistake with window regulators, so double-check before you order.

Trim level does not affect window regulator fitment on the 370Z — the door shell and regulator mechanism are the same regardless of whether the car is a base model, GT, or GT Edition. You may find that a higher-trim donor car has a slightly different wiring connector if it carries additional electric functions, so confirm with the breaker whether the loom connector matches your car if you're unsure. The mechanical regulator frame itself is what determines fit.

The 370Z received a facelift around 2013, but this primarily involved front-end styling and interior updates rather than structural door changes. Regulators from either side of that 2013 boundary are widely treated as compatible, but because running changes are not always publicly documented in full detail, we'd recommend asking the breaker to check the part number against your specific registration to be certain. Never assume fitment across any facelift boundary without that confirmation.

The Nissan 370Z was offered as a coupe and also as a roadster (convertible) variant, and the door and regulator assemblies differ between those two body styles. Make sure you source a regulator from the correct body style — coupe to coupe, roadster to roadster — as they are not interchangeable. Always confirm the body style with the breaker alongside the side (NS or OS) when requesting a quote.

Within the Z34 generation (2009–2020), regulators are broadly from the same platform, but without knowing the year you cannot be certain whether minor production changes affect your specific car. The risk with an unknown-year part is that subtle connector or bracket differences may only become apparent on fitting. We'd strongly recommend asking the breaker to verify the part against your registration number before you commit to buying.
