Rescue car window failure reason

Nowadays, the lifting glass of most road wreckers is electronically controlled. Rarely see the hand-operated lifting glass. Although the electric lifting glass is convenient and quick, once it involves electrical, it has a service life. There is a problem with the glass lifting, what components will be a problem? Today, the small company said that the car talked to you about the story of the window glass lifting.

Electric glass lifter switch

Nowadays, the left door glass lifter switch of most road wreckers can remotely control two doors, so the glass lifter switch of the left front door is theoretically the most vulnerable. This glass lifter switch controls the electric glass lifter. There are basically two kinds of electric lifters. One is the combination of the lifter motor and the lifter frame, and the other is separate. If there is a problem with the lift of the window glass, there may be three main components involved. The switch, the lifter motor and the lifter skeleton are theoretically less likely to be bad if the lifter frame is broken, unless it is a long-term irregular operation, or a foreign object is stuck, causing irregular displacement of the bracket on the skeleton, or the door. After being hit, the elevator frame is deformed. The frequency of the riser motor and the lifter switch is relatively high. If the bracket accessory is stuck in a foreign object, the power of the lifter will be blocked. The motor can work efficiently for a long time, but the skeleton does not work, it is easy to cause the motor to burn. Bad. The lifter switch is exposed in the car. If the window is closed, it is easy to float into the rainwater. The water stain enters the lifter switch. If it is not cleaned in time, the switch circuit board will be damaged and the switch will not work.

Integrated lifter motor + lifter frame

Generally, when going to the repair shop or the service station for maintenance, they usually let the owner replace the lift switch and the lifter assembly together when the economic conditions permit. This can completely solve the problem. If you want to save some, which part is out? If the fault is changed, if there is no fault, it can be judged by some small methods. If the lifter switch is broken, turn on the key vehicle to energize, then it is best to put the car on fire, let the vehicle electrical electricity pass, and then press the lifter switch to respond, the ear is attached to the car interior panel, the lifter switch The following 20 cm - 30 cm, to see if you can hear the sound of the lifter motor, if there is no movement, it is likely that the lifter switch is not energized, there is a fault. If the lifter switch is pressed, the sound of the lifter motor can be heard, or the take-off and landing speed is slow, or sometimes it can be raised and lowered, sometimes it is not possible, which means that the possibility of damage to the lifter motor is relatively large. When the lifter switch is pressed and the lifter motor does not respond, knocking on the car interior trim panel is probably the position of the lifter motor, and most of them can work. In this case, it can be basically judged that the lifter motor is damaged.

Separate glass lifter motor

When repairing such faults, in addition to the normal replacement of damaged parts, the working hours will be involved, the price of the parts should be reasonable, and the working hours should be within a reasonable range. When installing and disassembling the door trim, pay attention to the technique, because some of the door trim panels are linked by the buckle and the inner panel of the door, there is no fixing screw, so if the buckle is broken, if it is not replaced, the door trim It will be very loose, affecting the driving experience and driving safety.
