What to Do When Car Windows Won't Roll Up or Down
2 Answers
Solutions for car windows that won't roll up or down: 1. If the window lift motor is damaged or there's poor contact in the electrical control wiring harness, you need to visit a 4S shop or auto repair shop to replace the window lift motor; 2. If there's excessive dust or debris in the glass guide channel causing increased resistance, you need to clean out the dirt in the glass guide channel. The working principle of the window regulator is: when the motor is activated, it drives the reducer to output power, which pulls the steel cable to move the glass mounting bracket, forcing the door window glass to move in a straight line upward or downward. The window regulator consists of a motor, reducer, guide rope, guide plate, glass mounting bracket, etc. Depending on the material or manufacturing process of the guide rope, electric window regulators are divided into three types: rope-wheel type, flexible-shaft type, and plastic-belt type.
Having driven for over a decade, I've encountered numerous window lift issues. Start with the simplest: check if the switch was accidentally pressed or the lock function is activated; gently tap the switch panel—sometimes poor contact can be fixed with a simple touch. If the switch isn't working, inspect the fuse box—usually located under the driver's seat or in the engine compartment—find the fuse corresponding to the window, and replace it if blown. Listen for the sound of the lift motor; if there's no sound, the motor might be burnt out or stuck—temporarily use some lubricant spray on the window track to reduce friction. Preventive measures are crucial: clean the track dust weekly, check seals during the rainy season, as long-term neglect can wear out the motor. If it still doesn't work, head to a professional repair shop immediately—safety first, don't compromise driving comfort.
