How do I know what type of window regulator is in my door?

That’s a question, we hear a lot. The manufacturer, model and model year of your vehicle, including the door position will determine which mechanism is in your vehicles door. Each regulator is designed to fit a certain number of vehicles over a period of year ranges.

The size and weight of the glass, as well as the space inside the door panel will sometimes dictate the type and size of the mechanism that is used for a particular design.
