When it comes to daily maintenance, many people first think of the parts that are directly related to safety, such as the engine, brake system, tires, etc., but have you noticed the maintenance of the car door?
A car door is a small but complex part that includes door locks, glass regulators, crash beams, waterproofing and sound insulation etc. structure. If there is no collision, equipment such as horns, anti-collision beams and sound insulation layers will generally not cause problems, so what should be paid attention to in daily car door maintenance?
The hinges are often lubricated, and the doors can open and close freely
Because the doors are frequently opened and closed, some “Madaha” passengers or drivers will forcefully open and close the door or open the door If it is too large, the door hinges will wear out and deform over time, and the door will not close tightly. Always keep the door hinges lubricated to reduce wear and tear. When opening and closing the doors, fully close or fully open the windows. When closing the door with the window glass half-open, the vibration and impact are large, and the windows and doors are easily damaged; in addition, when closing the door, first gently open the door between 20??-30??, and then close it with a little force. Make the door hinges durable and the door open and close freely.
Apply protective agent to prevent weathering of weather strips
Rubber seal around door The strips play a role in improving air tightness. If aging and damage occurs, it will cause troubles such as water leakage in the compartment and increase of wind noise during driving. During maintenance, because the gaps of the sealing strip are easily blocked by sand and dust, the sand and dust should be cleaned with a brush frequently, and then a layer of high-permeability protective agent should be applied to prevent the aging of the sealing strip. The sealing strip needs to be checked, maintained and replaced regularly. When repairing the sealing strip, applying protective agent or washing the car, it is best to remove the sealing strip.
Common failures of window regulators
Three common types of window regulators Fault:
One is the abnormal noise of glass vibration, which may be caused by the looseness of the screw of the glass lifter. The solution is to tighten the screw of the lifter;
The second is that the glass lifter is stuck. It is because the glass mud tank is deformed or damaged, the fixing screw of the lifter is loose, the installation position of the guide rail is deviated or the glass lifter is damaged. The solution is to clean and replace the glass mud tank or loosen the glass installation screw to adjust the glass position;
< p>The third is that all the glass regulators cannot work. This serious situation may be that the ground wire of the combination switch falls off, the main power wire falls off, the relay is in poor contact, damaged, or the locking switch is in poor contact or not turned off. At this time, the circuit needs to be repaired. .
