Alfa Romeo 147 Window Regulators Available Here. A window regulator (laso lnowns as window winder) facilitates the raising and lowering of car windows. There are two types of window regulators: electric and manual. Electric regulators are operated by a button in the vehicle, while manual regulators are operated by turning a handle inside the vehicle. Electric window regulators can be sold with or without a motor, so it is important to check the description to avoid being surprised once the item is delivered. Many modern electric window regulators come equipped with an antipinch feature, which detects obstacles in the window's path and stops the window from closing, preventing a passenger's hand from getting caught. It’s important to note that window regulators are model-specific and differ based on the number of doors in the vehicle. Replacing a genuine regulator with an aftermarket one, is quite an easy task. For instance, the same car model will require a different regulator for the three-door version compared to the five-door version, as the window shapes are different. Generally, the three-door model has a larger front door to allow passengers to access the back seats. We have a very wide range of regulators available. Shop Window Regulators Ireland
