Cheap Nissan Micra Window Motor

No — the K11 (1992–2002) and K12 (2003–2010) are completely different generations with different door structures, so their window motors are not interchangeable. Always source a motor that matches your exact generation. Confirm the correct part with your breaker against your registration.

Yes, this matters for the front doors — a 3-door Micra has a longer front door than a 5-door, so the window regulators and motors differ between body styles. Rear door motors on a 5-door are their own fitment again. Always tell your breaker whether your car is a 3-door or 5-door when requesting a quote.

Both fall within the K12 generation (2003–2010), so there is a good chance the motors are compatible, but the K12 received a facelift in 2007 and some trim details changed around this period. Whether the motor crosses that facelift boundary without issue is something you should confirm with the breaker against both registrations before buying.

No — window motors are side-specific because the regulator mechanism runs in a particular direction for each door. In UK terms you need to specify NS (nearside, passenger/left) or OS (offside, driver/right) when requesting a quote from the breaker, as these are not interchangeable.

Trim level does not affect the physical fitment of the window motor — what matters is the generation, the body style (3-door or 5-door), and the side (NS or OS). Higher trims may be more likely to have electric windows as standard, but the motor itself fits by door position, not trim badge. Confirm with your breaker that the donor car has electric windows if you are fitting to a car that already has them.

The K13 (2010–2017) is a different generation from the K12 (2003–2010) and the two are not the same platform, so cross-generation fitment is unlikely to be straightforward. Stick to sourcing a motor from a K13 of the correct body style and side to be safe, and confirm compatibility with the breaker using your registration.
