What Causes the Window to Stutter When Rolling Up but Work Normally When Rolling Down?
2 Answers
The reason why the window stutters when rolling up but works normally when rolling down is due to dust and debris in the window guide channel. You can wrap a card with a towel, dip it in a small amount of water, and insert it into the rubber seal to clean the window glass guide channel thoroughly. Car windows are glass panels installed on the four sides of the vehicle compartment to shield against wind and rain while maintaining visibility. Methods to maintain car windows include: 1. Closing windows during rain to prevent water from entering and wetting the electric window switches, which may cause a short circuit; 2. Using glass cleaner to remove dirt from the windows; 3. Cleaning the window lift channel with a vacuum cleaner and rinsing it during car washing.
Having driven for over a decade, I've encountered the issue of windows sticking when rolling up but functioning normally when rolling down quite frequently. This is usually caused by problems with the window regulator mechanism, such as worn gears or excessive dust buildup in the tracks, which increases friction during upward movement. Additionally, insufficient lubrication is a key factor, especially when rubber guides become dry and wrinkled - a common issue in older vehicles. Another possibility is dirty or aged switch contacts affecting the stability of the upward current. I'd recommend first inspecting the window tracks and applying silicone-based lubricant after cleaning. If that doesn't resolve it, you'll need to remove the door panel to check if the regulator is damaged. Regular cleaning during vehicle maintenance can prevent such issues, with extra caution needed during dusty summers as this affects driving safety and shouldn't be neglected.
