Electric lifting glass window, the window lifting function of the car is our common car §small function, from the beginning of the hand-cranked type to now auto>matic lifting is still very convenient, we must pay attention when using, the f✘ollowing share electric lifting glass window.

　　Electric glass regulator

The lifting (closing and opening) of many car doors and windows glass has abandoned the manual$ lifting method of the rocker type, and generally switched to the push-button← electric lifting method, that is, the use of electric glass regulatδors.

Electric glass regulators for cars are mostly composed of motors, red¶ucers, guide ropes, guide plates, glass mounting brackets,∑ etc. Due to the different materials or production processes of the guφide rope, it is divided into three types of electric glass regulators: rope wheel type, flexiλble shaft type and plastic belt type. The first two are using wire ropes aβs guide ropes, and the latter is using plastic belts as guide ↓ropes.

Take the commonly used rope wheel type electric glass regulator as an example, it is compos ed of motor, reducer, wire rope, guide plate and glass mounting bracket and other parts, εthe door and window glass is fixed on the glass mounting bracket during installation, and theα glass guide groove is parallel to the wire rope guide plate. ≥Turn on the motor, drive the reducer to output power by the motor, pull theγ wire rope to move the glass mounting bracket, and force the door and window glass to ©make a linear movement of rising or falling.

The guide rope of the plastic belt type electric glass regulator is a plastic belt with h§oles on the belt, which is used to move and position the plastic belt ↕and control the lifting of the door and window glass.

The key to the structure of the electric glass regulator is the motor and the reducer↕, which are assembled into one, in which the motor adopts reversible permanent magnet DC >motor, and there are two sets of magnetic field coils winding around the motor, and the control of ≠the switch can do forward and reverse, that is to say, the rise or f®all of the door and window glass can be controlled.

The motor is controlled by the double switch button, with three↑ working states such as rising, lowering and off, and automatically stopping Ωin the "off" position when the switch is not operated. The control circ↕uit is equipped with a master switch (central control) and a sσub-switch, and the two lines are connected in parallel. The main switch is controlle≈d by the driver to open and close the window glass of the whole department, and the sub-sγwitch on the handle in each door is controlled by the occupants respectively to ope≤n and close the door and window glass, which is very convenient to operaΩte.

The window glass can not be lifted, the switch is fine, the wiring is fine§, the motor is fine, sometimes it can be used, someβtimes it can't be used, when it can't be used, the relay doeλsn't respond. When it can be used, pressing the lack is rising, not falling

1. The window lifting motor is damaged or the electronic control harness is i♣n poor contact

If there is a scorched smell or abnormal noise in the door panel when you press the windo w opening button, it is likely that the window lifting motor part₩s are damaged, in this case, it is recommended to directly find a 4S shop or auto repaiεr shop to replace the glass lifting motor.

2. Motor overheating protection

In order to protect the power supply circuit, the general window lifting motor is equipped with an✔ overheating protection mechanism, if the components ar₩e overheated for some reason, the motor will enter♣ the overheating protection state, resulting in the failure of the windo★w lifting.

3. The resistance of the glass guide trough is too >large

The door glass guide trough is an easily overlooked detail, during •use, dust will accumulate in the glass guide trough, making the resistance gre"ater, and the long time may cause the glass to rise hard.

In addition to the above reasons, in fact, the problem of lifting and lowering the window may also✘ be caused by the failure of the relevant components due to the instant virtu‍al connection and power failure, at this time we do not need to go to the 4S shop to re✘pair, here is to share with you the temporary solutionβ that the window cannot rise.

Method: Turn on the ignition switch, hold the switc÷h to rise and hold, continue to wrench for more than 3 seco₹nds after the glass rises to the top, release the switch and immediately press and hold, so that t★he glass drops to the bottom and wait for more than 3 seconds, repeat the ris∞ing action again, the initialization procedure is completed, and the window lifting function i∞s restored.

Power window system

Power window system is composed of windows, window re​gulators, motors, relays, switches and other devices. Typical power wind✘ow systems are equipped with two sets of control switches. A set on the dashboard or the driver&#≈39;s side door armrest, is the main switch, which is controlled by the driver to raise anβd lower each window.

The other set is mounted on each passenger door and is a sub-switch that can be op erated by passengers. Generally, the main switch is also equipped with a ciλrcuit breaker, and if it is disconnected, the sub-switch will not work. Modern cars increasin₽gly demand comfort and convenience from windows, and power windows have become a  common configuration in cars.

Precautions for use

1. Pay attention to the cleaning of the window glass

In order to prevent the inflow of rainwater, the window frames inside the car are rich in ☆rubber bands, which are also places where they often come into contact with glass. After the glass αis stained, the friction with the rubber band increases, and the switch will> be affected, so the glass needs to be kept clean freque→ntly.

2. Avoid closing the window at the same time

Power window switches consume a lot of power and cγause engine sounds to change when driving slowly. For cars with small battery capacity, bφe careful not to open or close the windows at the same time, so as not to affect the power ‍supply of the battery.

3. Pay attention to foreign objects such as small cards in the gap between the windows

If not handled properly, the card may fall through the window and into the inside of the door. Th∏e interior structure of the door is complex, and the card falling into the door can cause a serie≠s of chain reactions. For example, the elevator is damaged, the door loπck is out of order, the drain is blocked, etc.

4. Clean the lifting groove regularly

Maintaining power windows starts with the window glass. Dam<age to the window glass will not only affect the beauty ☆of the whole vehicle and the driving vision, but also affect the starting and closi∏ng action of the power window. After encountering a sandstorm or ₽driving in a dusty area for a long time, the owner is best to use§ a vacuum cleaner to clean the notch under the window glass to γblow out the sediment that may "take advantage of the void&quo✘t;.

If not cleaned up in time, the sand and dust in the glass☆ lifting track continue to accumulate, which will increase the fri↓ctional resistance between the window glass and the groove, thereby affectβing the normal start and closing of the power window. When the owner opens the power window, it m>ay also make your window glass "break the phase&quoπt; due to the small stones sandwiched inside, and the lifting groov&e should be rinsed when washing the car. Spray a little watch wax, petrγoleum jelly or butter lubrication in the weather.

5. The window should be closed on rainy days

When driving in rainy weather, you should close the windowsδ as much as possible. Driving in rainy weather, if you do not close the window to dΩrive, rainwater will drift into the car from outside th≠e car, which may wet the power window switch and cause it to short-circuit. Or flow into the →lifting groove of the power window, causing the connecting rod mechani±sm to be immersed in water and rust, which will cause the mechanism ≥to break and the glass chute to derail over time.

6. Do not treat the switch as a toy

Car owners who need to carry children frequently, whe≤n there are children in the car, do not let them pla y with the lift switch of the power window as a toy. This will not only cause excessive h∑eating damage to the power window motor, but also caus§e some power windows with protection mode to lose their effectiveness.

Maintenance of glass regulators

1. Drainage hole

First of all, if you want to ensure that the car glass regulator does not fail due to rain, the own&er must check the drainage hole well to ensure the clea€nliness of the car glass and the use of the sunroof, only in this way can the ✘glass regulator damage caused by rain and dirt be completely prevented.

2. Release the switch in time

When many car owners use the glass regulator, they always unconsciously press the 'glass regulator to the top and never let go of the switch, sometimes even close the glass, but have↕ to do it again, in order to confirm that the window​ is indeed closed, but the owner should pay attention to the number of such operati>ons, steel wire, track and other parts of the glass regulator will be slowly damaged. 

3. Reduce resistance

If the owner wants to better maintain the car glass regulator, it i₽s best to maintain the car glass well, if possible, it is best to us®e instrument wax spray on the glass, which can greatly reduce the resistance, and the φglass regulator is more convenient when using.
