What to Do When Car Windows Won't Roll Up or Down

[HaydenAnn]

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.
