What causes the window glass of Haval H6 to shake when rolling up and down?
4 Answers
Haval H6 window glass shaking has two possible reasons: 1, the glass curvature is incorrect, causing interference and shaking when halfway rolled up. 2, the glass bracket is loose, or the window regulator is loose. Suggestion: Visit a professional auto glass shop for inspection and determine the cause before repair. Additional information: It is normal for the Great Wall Haval H6 to develop window noises after a certain period of use. Generally, family cars may experience varying degrees of electric window noise after two to three years of use. This is because, over time, the window's outer sealing strips age, leading to poor sealing.
I've also encountered the issue of shaky window movement while driving, especially a few times with my friend's Haval H6. The root cause of this shaking is the loss of stable support for the glass within the guide channel, often due to loosened screws on the window regulator's rail—similar to the wobble of a loose drawer slide. Continuous vibration from window operation can naturally loosen these screws over time. Other possibilities include deformation of the regulator bracket or increased gear clearance in the motor. If water enters the door during car washing, rust on the rails can worsen the shaking. My advice is not to ignore it—head to a repair shop promptly to have the door panel removed. They should inspect the screws and bracket condition of the window regulator assembly, tightening or replacing parts as needed. Stable windows are crucial for both driving safety and noise insulation, so this isn't something to take lightly.
With over a decade of experience repairing cars, I'm extremely familiar with the Haval H6's window system. If the window glass wobbles during operation, it's most likely due to a deformed window regulator bracket – just like human joints, deformation leads to instability. It could also be caused by loose clips on the lower edge of the window glass or aged/cracked guide channel seals, making the glass sway when moving along the track. Another common issue in older models is cracked welding points on the motor bracket. Last time, a customer complained about increasingly loud operation noises – turned out to be unbalanced resistance from lack of lubrication in the guides. The repair isn't complicated: remove the door trim panel, reinforce where needed, lubricate where required, and it can be fixed in half an hour.
The root cause of window shaking during operation lies in the misalignment of the lifting system. Focus on inspecting three key areas: whether the mounting bolts of the window regulator bracket are loose, if the guide rail bushings are worn through, and if the glass positioning clips are deformed. Particularly when shaking occurs after rainy days, it's usually caused by uneven friction due to water-expanded bushings. Another hidden reason could be detached sound insulation foam inside the door panel tangling with the lifting mechanism. For DIY solutions, you can try cleaning the glass guide channels and applying silicone-based lubricant to the rails, but critical components require professional tools for proper inspection. This fault has relatively low repair costs, but prolonged neglect may damage the motor.
