What Causes Slow Window Movement?
2 Answers
Reasons for slow window movement: 1. Possible malfunction of the window regulator; 2. Potential motor aging leading to insufficient power; 3. Overly tight window felt channels or foreign objects in the window track; 4. Aged outer water seal strips creating excessive resistance or deteriorated inner dust seals. Prompt inspection and repair at a service center is recommended. Solution: Apply window lubricant by first lowering the window and thoroughly cleaning the window surface, rubber seals, and crevices of dust and stains. Shake the window lubricant well before use, then insert the applicator tube into the nozzle. Evenly spray the lubricant along the window rubber channel, allow it to sit briefly, wipe away excess lubricant with a cloth, then test window operation.
I've found that slow window operation is mainly related to a few areas. First, the window tracks and seals accumulate too much dust or dry out over time, which can cause the glass to get stuck. What I often encounter is dirt getting inside the door after rain, which dries and forms hard lumps blocking the path. You need to clean the tracks with a damp cloth and spray some lubricant to make it smooth again. Secondly, the window regulator motor might be aging or worn out, lacking enough power to move the glass, especially noticeable in cold weather or rain. Additionally, poor contact in the switch connectors or insufficient power supply can also be issues—check the battery charge and make sure wiring connections aren't loose. If neglected for too long, it might even cause the window to not seal properly after raising, leading to leaks, so it's best to have a professional inspect and replace parts if needed.
