The doors of an MX5 NBFL (2001–2005) contain various rubber seals, guides, and mounting parts that ensure a good seal and smooth window operation. In this category, you’ll find, among other things, Origineel Mazda window seals, door seals, door film, and power window mechanisms. If the window operates slowly, crookedly, or not at all, be sure to check the power window system for wear, poor connections, or a faulty motor.
