What Causes the Power Window Failure in Buick Excelle?
2 Answers
Generally speaking, the causes and solutions for power window failure or malfunction are as follows: 1. Aging rubber seals: Aged, dirty, or deformed window rubber seals can create resistance when raising or lowering the glass. For aging or deformation issues, it's best to replace the seals. If they're just dirty, cleaning them thoroughly should suffice. Spraying some dashboard wax or applying talcum powder to the seals usually yields good results. 2. Dirty window tracks: Dirty window lift tracks. This is also a lubrication issue. Cleaning the tracks and applying grease can resolve the malfunction. 3. Battery power issues: Low battery voltage may also cause difficult or failed window operation. When operating windows with the engine off, the system draws power from the battery. Insufficient battery charge can lead to window operation difficulties.
Hey, my Buick Excelle's power window has failed a few times. Generally speaking, the most common issue is a blown fuse. You can check the fuse box yourself to see if the fuse corresponding to the window is blown and replace it if necessary. If the fuse is fine, then it might be a faulty switch button—overuse can cause the button to age and result in poor contact. The window motor could also be damaged, especially after frequent use, leading to burnout or rust jamming. Also, loose or short-circuited wiring harnesses inside the door can prevent current from passing through, so check for corroded connectors. I suggest not messing with it yourself—getting stuck in rainy or winter conditions can be particularly dangerous. Just take it to a repair shop where they can accurately diagnose the issue with proper tools.
