Vauxhall Cavalier Window Winder Motor Replacement Parts

The Cavalier ran across two well-known UK generations: the Mk2 (1981–1988) and the Mk3 (1988–1995), and the generation is the single most important fitment factor for a window winder motor. Door mechanisms, mounting points, and regulator designs differ significantly between these two generations, so a Mk2 motor will not be a straight swap into a Mk3 and vice versa. Always quote your generation to the breaker alongside your registration.

Both 1989 and 1992 fall within the Mk3 generation (1988–1995), so you are working within the same core body generation, which is a good starting point. However, you must also confirm the door count and which side you need, as 3-door and 5-door front door motors are not interchangeable, and NS (nearside, passenger side) and OS (offside, driver side) units are side-specific. Confirm the exact details with the breaker against your registration before purchasing.

A 1987 Cavalier is Mk2 and a 1989 Cavalier is Mk3, so these sit either side of the generation boundary at 1988, meaning the motors are very unlikely to be interchangeable. Even if a motor looks visually similar, mounting points and regulator fitment commonly differ across this boundary. Route this cross-generation question directly to a breaker who can compare the two donor vehicles against your registration.

Trim level — whether L, GL, GLS, or CD — does not affect window winder motor fitment on the Cavalier; fitment is determined by generation, body style, and side (NS or OS). You may find cosmetic differences between donor cars pulled from different trims, such as interior finish or door card style, but the motor and regulator mechanism itself is not trim-specific. Focus your search on matching generation, door count, and side rather than trim.

Yes, side is critical — NS (nearside, passenger/left) and OS (offside, driver/right) window winder motors are side-specific and will not swap between doors. Always tell the breaker clearly which side you need, along with your generation and whether your car is a 3-door or 5-door, as front door motors can also differ between those body styles. Getting the side wrong is one of the most common reasons a used motor fails to fit.

No — engine size has no bearing on window winder motor fitment on the Cavalier. What matters is the generation (Mk2 1981–1988 or Mk3 1988–1995), the side required (NS or OS), and the door count (3-door or 5-door). Provide your registration to the breaker so they can cross-reference the exact donor vehicle.
