What Causes the Power Window Failure in Nissan Sunny?
2 Answers
Nissan Sunny power window failure may be caused by aging and deformation of the glass sealing strip, foreign objects in the window lifting guide rail, etc. Here are detailed explanations and solutions: Aging and deformation of the glass sealing strip: If the glass sealing strip (including the inner trim strip) is aged, excessively dirty, or deformed, it can create resistance to the window's upward or downward movement. Generally, if the strip is aged or deformed, it is best to replace it with a new one. If it is just dirty, cleaning it should suffice. Spraying some dashboard wax or applying talcum powder (to act as a lubricant) on the glass sealing strip can often yield good results. Dirty window lifting guide rail: This is also a lubrication issue. Cleaning the window lifting guide rail and applying grease can eliminate the fault.
After years of repairing cars, I've encountered numerous window lift issues with the Nissan Sunny, primarily due to several reasons. The lift motor, being the core component, tends to age or burn out over time, especially in winter when low temperatures can cause it to jam upon startup. The switch buttons are also problematic; oxidized contacts lead to poor connectivity, resulting in no response when pressed. Wiring issues are common too, with short circuits or open circuits often occurring, especially when moisture inside the door corrodes the wire ends. Don't overlook the transmission mechanism either—dust and debris in the tracks can jam the glass movement, with squeaking sounds serving as a warning. Fuse blowouts are even more common, cutting off instantly due to excessive current, so it's essential to check the fuse box. Additionally, a faulty control module can cause misoperation. For daily maintenance, I recommend car owners regularly clean dust from door grooves, lubricate the tracks, avoid letting children press the switches forcefully, and first check the switches and fuses when problems arise. For more complex issues, it's best to seek professional repair services.
