What are the reasons why the car window cannot be raised or lowered?
2 Answers
There are several reasons why a car window cannot be raised or lowered: 1. Aging, dirty, or deformed glass sealing strips (including inner strips): These create resistance when raising or lowering the window. If they are aged or deformed, replace the sealing strips. If they are dirty, spray some dashboard wax or apply talcum powder to the strips. 2. Dirty window lift rails: Clean the window lift rails and apply lubricating grease to eliminate the issue. 3. Low battery power: Operating the window when the engine is off consumes battery power. If the battery is low, it may be difficult to raise or lower the window. 4. Motor failure: If there is sufficient power and no resistance, but the window is still difficult to operate, the motor may be faulty. 5. Window regulator failure: Issues such as faulty lift rails, cable problems, or slider malfunctions may require replacing the window regulator. 6. Improper glass sealing strips: If the strips are not fitting properly, you can adjust their shape using scissors or a knife as a DIY solution.
I remember a while ago my car window suddenly got stuck, no matter how much I pressed the button, it wouldn't respond—what a headache. At first I thought the switch was broken, but after taking it apart the contacts looked fine. Turned out it was just a blown fuse—replacing it fixed the issue. If you don't hear the motor humming when pressing the button, the motor might be burnt out or there could be a wiring short, especially in older cars where connectors tend to wear out. If the window struggles to move, accumulated dust in the tracks or overly thick window tint can cause jamming—a spray of anti-rust lubricant can help. Safety first: avoid forcing it to prevent further damage, and ideally have a friend check the voltage with a multimeter. Minimizing window operation during rainy weather can reduce problems—addressing such issues early saves hassle.
