Why is the window rolling up and down slowly?
1 Answers
The reasons for slow window operation: 1. The window felt channel is too tight or doesn't match the curvature of the glass; 2. The window regulator has become loose over time, causing misalignment, or the cable has developed burrs, increasing resistance; 3. The regulator motor has aged and lacks sufficient power; 4. The outer water seal strip has aged and creates resistance, or the inner dust seal strip has deteriorated. It's recommended to visit a repair shop for inspection. Automotive glass is manufactured by heating it to near softening temperature in a furnace, then rapidly transferring it to cooling zones with varying intensities, creating different stress levels between the main viewing area and peripheral zones. Typically, this process produces zone-tempered glass.
