Operate the power window correctly to avoid faults in used cars.

Small details in daily use have a great impact on the service life of the power windows of a used car. First, don't let the power windows work when the car is not started. Many people are used to adjusting the windows before starting the used car. At this time, the battery power is only used without charging, which is easy to cause excessive power consumption. For the old battery of a used car, this may even affect the starting of the car. Second, clean the window guide rail regularly. You can use a soft cloth dipped in clean water to wipe the guide rail every month to remove dust and debris. This can reduce the friction between the glass and the guide rail. Third, don't use the power windows when it's freezing. In cold winter, the glass and sealing strip may be frozen together. Forcing the window to rise will pull the sealing strip or damage the motor. You can turn on the warm air to defrost first, and then operate the windows after the ice melts. These small details seem trivial, but they can effectively protect the power windows of the used car.

For many used car owners, power windows are such a common feature that we often take them for granted. We roll them up and down casually, but wrong operation methods can easily cause faults. The power window components of new cars are all in the best condition, but the power window system of a used car, including the motor, switch and glass guide rail, may have already had certain wear. Repairing power windows is not cheap, but as long as you use the right method, these faults can be completely avoided. Let's talk about how to correctly operate the power windows of a used car to keep them working well.

The biggest mistake people often make when using the power windows of a used car is forced operation when the window is stuck. Over time, dust, leaves and even small stones may get stuck in the window guide rail, causing the window to rise or fall slowly or get stuck halfway. At this time, many people will hold down the switch hard, trying to "force push" it through. This is fatal to the window motor of a used car. The motor has been used for several years and has wear. Forced stress will make it overheat, and even burn out directly in serious cases. The correct way is to stop operation immediately. First, use a soft brush to clean the guide rail gently. If it is still stuck, drive the used car to repair. Forcing it will only turn a small blockage into expensive motor repair.

When using the power windows of a used car, you must pay attention to the change of resistance. If you feel that the window rises slower than usual, or there is obvious "stuck" and strange noise, don't operate it repeatedly. This abnormal resistance is usually a signal of problems. It may be that the guide rail is rusted, the rubber sealing strip is aged and stuck to the glass, or the motor starts to have problems. The rubber parts of a used car are originally more likely to age and harden, which will increase the friction resistance of the glass. Repeated operation with resistance will accelerate the wear of the motor and gears. When you find this situation, first apply a little window lubricant to the guide rail. If the problem still exists, find a professional to check the window system of the used car. Finding and dealing with it early can avoid bigger troubles.
