The window mechanism of the MX5 NB (1998 - 2000) allows for smooth and controlled opening and closing of the side windows. Inside the doors are several parts, such as guides, cables, mounting points and moving components that are used daily when the windows are operated. Through years of use, these parts can wear out, causing the window to move less smoothly, skew or even get stuck. The mechanism works closely with the electric window controls, so a failure can sometimes have both a mechanical and electrical cause. A properly functioning window mechanism adds to the car's ease of use and ensures that the side windows close neatly for a good seal against wind, rain and driving noise.
