Front left window regulator for the Mercedes-Benz R107 SL.

Part numbers

OE A1077201246 (mirrored from the confirmed right side number, 1077200846 or A1077201246 depending on manual or electric spec). No confirmed single number for left specifically, ask us to check yours.

Fits

All R107 variants, 1971 to 1989, front left door position. On left-hand drive cars this is the driver's door, on right-hand drive cars the passenger door. R107s came with both manual and electric window options depending on trim and year, confirm which yours has, send your VIN if unsure.

Why it matters

This is the most common electrical failure on the R107. The regulator mechanism wears and the window either drops, sticks, or stops responding altogether. It's common enough that we stock both sides.

What you get

One front left window regulator.

Give us your VIN if you're not certain on fitment, we'll check it before anything ships.
