What Causes the Car Not to Start and Windows Not to Close?
2 Answers
When a car fails to start and the windows won't close, it is usually due to a depleted car battery. Here are some maintenance tips for car batteries: 1. In-car electricity usage: To maintain the car battery, avoid activities like listening to the radio loudly, charging your phone, or using an air pump while the engine is off. Prolonged use of these features can drain the battery, and frequent depletion significantly reduces its lifespan. 2. Long-distance highway driving: Regularly driving on highways has many benefits. It not only helps remove carbon deposits from the vehicle but also fully charges the battery. Generally, driving on the highway for over an hour can fully charge the car battery, keeping it in optimal condition. 3. Avoid prolonged parking: If the car is not used for an extended period, disconnect the battery cables or start the vehicle every two weeks and drive it for several dozen kilometers to ensure the battery remains functional. 4. High-power electrical connections: Many modern car accessories, such as car refrigerators, vacuum cleaners, and air pumps, have high instantaneous power consumption. Avoid powering these devices directly from the car battery.
I just encountered this situation not long ago. Actually, when both issues occur simultaneously, it's highly likely a battery problem. The car not starting is often due to a dead battery, which can also cause the power windows to fail. Try checking if the headlights turn on when you attempt to start the car. If the lights are dim or don't turn on at all, there's an 80% chance the battery has reached the end of its lifespan. Another possibility is a blown main power fuse, which can affect the entire vehicle's electrical system. Also, inspect the ignition switch—last time, oxidized contacts on the switch prevented my car from starting and even caused the window regulators to stop working. I recommend performing a jump-start test. If the car starts, it means the battery needs replacing. If the windows still don't work after jump-starting, you'll need to check for short circuits in the window regulator wiring or a faulty motor.
