Window regulators are essential for your BMW 3 Series. They were invented in the 1960s as a mechanism to open your vehicle windows automatically rather than manually. This is done by sending a signal to the window glass when you operate the button.

Although this is miles easier than doing the action manually, the window regulator mechanism can often fail. This can be caused by many factors but the most common is simply just wear and tear. It's made up of a pulley system which is responsible for moving the windows up and down, this can often be overused and fail.

The main symptom of a failed window regulator for your BMW is fairly obvious but there are ways to detect its failing before it fully stops working. These include:

• Inconsistent opening and closing speed
• Misalignment in the window
• Odd noises when opening or closing
• The window won't go all the way up

If you notice any of these signs on your BMW 3 Series’s windows, it's probably time to replace your regulator. Buy window regulators here at Spares Hut for both the best quality and prices. What's more, when you purchase this product you get FREE next day delivery if you order before 2 pm.
