What are the reasons why the car window cannot be rolled down?
2 Answers
There are two main reasons why the car window cannot be rolled down: 1. Electrical failure, such as a burned-out motor; 2. Mechanical failure, such as the glass being stuck by an object; 3. Insufficient lubrication inside the door's window regulator. It is necessary to check the lubrication inside the door's window regulator, and if it is insufficient, the inner cover should be removed to add oil. Additional Information: 1. The electric window system consists of the window, window regulator, motor, relay, switch, and other components. Generally, the electric window system is equipped with two sets of control switches. One set is installed on the dashboard or the driver's side door armrest, serving as the main switch, which allows the driver to control the raising and lowering of each window. The other set is installed on each passenger door, serving as the sub-switch, which can be operated by the passengers. Usually, the main switch also has a circuit breaker switch. If it is turned off, the sub-switches will not function. 2. The window seals are constantly eroded by windblown sand or rainwater, which can lead to aging of the rubber seals over time. When dirt accumulates inside, it can affect the window's ability to rise or descend smoothly. Sometimes, when rolling the window up or down, a "squeaking" sound can be heard. Therefore, it is advisable to occasionally clean the dirt inside the rubber seals with a cloth to maintain a clean environment. 3. In general, every component in the car should be taken care of regularly. Of course, this does not mean overdoing it, but proper maintenance can definitely save a lot of money on future repairs and upkeep.
When my car window won't roll down, my first reaction is to check if the switch responds. If there's no sound, it might be a blown fuse, located in the fuse box under the dashboard. It could also be due to dust buildup or freezing in the tracks—try cleaning with a cotton swab or spraying some lubricant. Motor failure is common; if the motor won't turn or makes strange noises, it's quite troublesome. Regular maintenance is crucial—frequently opening and closing the window prevents sticking, and lubricating the tracks every six months helps. If you can't fix it yourself, don't force it; go to a repair shop immediately. Safety first, to avoid being unable to open the window in an emergency for escape.
