51357202481 BMW EL.WI.WINDER

This part is essentially the mechanical system that actually moves your rear left window up and down when you hit the switch. The switch just sends the electrical signal, but this regulator uses a motor and a system of cables, gears, or arms – depending on the vehicle – to physically raise and lower the glass. It's a pretty complex little assembly, really. It’s part of the overall power window system, obviously. But specifically, it’s the muscle that gets the window moving. Without it, your window switch won’t do a thing. It takes the electrical power and converts it to mechanical motion. It also holds the window glass securely in the door frame, keeping it aligned properly. Well, it's important for obvious reasons – you want to be able to open and close your window! But beyond that, a failing regulator can cause a lot of headaches. You’ll notice if it’s starting to go because the window might get slower and slower, or it might make a grinding noise. Sometimes it’ll go up, but not down, or vice versa. Eventually, it'll likely stop working altogether. It’s one of those things you don't think about until it's broken. We carry a good selection of these, and you can often find the exact part you need at Fixparts Online, which can save you a trip to the dealership. It’s a pretty straightforward repair, but definitely something you want to address before it leaves you with a window stuck in the open or closed position.
