What is the reason for the left front window not being able to roll down?
1 Answers
If only the left front window cannot roll down, you can check the window control switch to see if the power to other control switches has been turned off, preventing other doors from controlling the window movement. The reasons why a car window cannot roll up or down are as follows: 1. The window seal (including inner trim) is aged, dirty, or deformed, which creates resistance when the window moves up or down. Generally, if it is aged or deformed, it is best to replace the seal; if it is dirty, simply clean it. Spraying some dashboard wax or applying talcum powder (for lubrication) to the window seal can usually be very effective. 2. The window guide rail is too dirty: This is also a lubrication issue. Cleaning the window guide rail and applying grease can resolve the problem. 3. Check if the battery is low on power: When rolling the window up or down without the engine running, the power is drawn from the battery. If the battery is low, the window may struggle to move. 4. Motor failure: If there is sufficient power and no resistance, but the window still struggles to move, it is likely a motor issue. 5. Window regulator failure: This includes issues with the window guide rail, cable, or slider, and the only solution is to replace the window regulator. 6. Improper window seal: Some cars may have improperly fitted window seals. In such cases, you can DIY by using scissors or a knife to adjust the shape of the seal.
