Fitment on a used window winder motor varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
The Ford Sierra ran from 1982 to 1993, with a significant facelift in 1987 that revised the door skins and interior on several body styles, so a motor from a pre-facelift car (1982–1987) may not be a direct swap into a post-facelift car (1987–1993). Generation and body style are the key fitment factors here, and crossing that 1987 boundary is exactly the kind of detail you should confirm with the breaker against your registration before ordering.
Yes, it matters — the front door on a 3-door Sierra is a longer door than the front door on a 5-door, so the window mechanism and motor are specific to the door count. Always tell the breaker whether your car is a 3-door or 5-door, as well as whether you need the nearside (NS, passenger left) or offside (OS, driver right) motor.
Absolutely — window winder motors are side-specific, so a nearside (NS, passenger side) motor will not be the same unit as an offside (OS, driver side) motor. When you contact the breaker, confirm which side you need along with your registration so they can match the correct part.
Trim level does not affect the fitment of the window winder motor itself — what matters is the generation, door count, and side (NS or OS), not whether the car is a base L, GL, Ghia, or XR4i. That said, if your car has electric windows you obviously need an electric motor, and if you are sourcing from a car that had a different window-operation setup, confirm this detail with the breaker to make sure the motor type matches your door.
The Estate, saloon, and hatchback body styles each have their own door structures, so front door motors should share fitment within the same generation as long as door count and side match — however, rear doors differ between body styles and are not interchangeable. Confirm the exact body style with your breaker alongside the year and side to be safe.
The 1987 facelift is the key boundary here: a 1986 car is pre-facelift and a 1988 car is post-facelift, and door construction changed across that divide. Whether the motor physically interchanges across that 1987 boundary is something you should check with the breaker using both registrations, as they will be able to compare the exact part numbers and door types.
