Fitment questions

Does the Mercedes-Benz SLK actually have window switches?

Yes, all generations of the SLK have electric windows as standard, so window switches are a genuine and common part on this model. The SLK is a two-seat roadster with just two doors, so there are two window switches to consider — one for the driver's side (OS, offside) and one for the passenger side (NS, nearside). Make sure you specify which side you need when requesting a quote from a breaker.

Will a window switch from a first-generation SLK (R170, 1996–2004) fit a second-generation SLK (R171, 2004–2011)?

The R170 and R171 are entirely different generations with different interior designs, so the window switches are not interchangeable between them. The R170 ran from 1996 to 2004 and the R171 from 2004 to 2011, and breakers will need your registration to confirm exactly which generation your car is. Always confirm fitment against your registration with the breaker before purchasing.

Does a window switch from a pre-facelift R171 SLK fit a post-facelift R171?

The R171 received a facelift in 2008, and while some interior components carried over, it is not guaranteed that window switches are identical across that boundary. You should confirm with the breaker whether the specific switch they have matches your pre- or post-2008 build, as minor detail changes can affect fitment or appearance. Route your registration to the breaker so they can check against your exact car.

Will a window switch from a third-generation SLK (R172, 2011–2016) fit my car?

The R172 ran from 2011 until the SLK was rebadged as the SLC in 2016, and its interior is distinct from the earlier R170 and R171 generations, so switches from an R172 will only suit another R172. If you have an R172, confirm your exact build year with the breaker as there was a facelift around 2016, though if genuinely uncertain of internal changes across that period the breaker should verify against your registration. Never assume cross-generation fitment without checking.

Does it matter which trim level my SLK is — for example SLK200, SLK250, or SLK350 — when sourcing a window switch?

Engine variant and trim level do not affect window switch fitment on the SLK — the switches are determined by generation (R170, R171, or R172) and side (NS or OS), not by whether you have a 200, 250, or 350 model. You may find minor cosmetic differences such as finish or button style between trim grades, but the fitment itself is the same. Focus on matching the generation and side, and let the breaker know if a particular finish is important to you.

I need to know if the window switch needs to be driver's side or passenger side — does it matter on a UK SLK?

Yes, side matters on the SLK even though the switches are sometimes similar in appearance, as the driver's door switch (OS, offside, right-hand side on a UK car) often includes the master controls for both windows, whereas the passenger switch (NS, nearside, left-hand side) is typically a single-window control. Always specify OS for driver's side or NS for passenger's side when contacting a breaker, along with your generation (R170, R171, or R172). Getting the side wrong is one of the most common sourcing mistakes, so double-check before ordering.
