What is the rear door R
The "R" sign on the back door of a car usually indicates that the car is right-hand drive, that is, the driver's seat is located on the right side of the vehicle . However, based on this logo alone, we can't tell exactly the specific model of this car, as many car brands offer right-hand-drive models, such as Toyota, Honda, Chevrolet, etc .
In addition, the "R" button on the doors of Mercedes-Benz cars usually stands for the "Reverse" function , which activates the car's reverse mode .
However, specific features and operation may vary from vehicle to vehicle and owners are advised to refer to the detailed user manual of their respective vehicle or contact the vehicle manufacturer for accurate information .
The main reasons why the rear door of a car cannot be closed include the following :
Insufficient or faulty lock motor pull : Insufficient or damaged lock motor pull will cause the rear door to fail to lock. In this case, it is recommended to go to the 4S shop to replace the new door lock motor .
lock rust or corrosion : If the lock rust or corrosion, the lock will not work properly. Replacing the lock with a brand new one can solve the problem .
line problem of the central control system : poor line contact, short circuit, or open circuit of the central control system may also cause the rear door cannot be locked. Checking and fixing wiring problems can solve this problem .
lock mechanism resistance : the internal resistance of the lock mechanism increases, usually due to the rust of the mechanism. Professional maintenance can solve the problem .
lock motor lock position offset : lock motor lock position offset will cause the rear door cannot be locked. Go to the maintenance site to adjust and return to normal .
Remote lock failure : A remote lock failure or aging antenna of the remote transmitter can also cause the rear door to fail to lock. Mechanical keys can be used to lock .
magnetic field interference : there is strong magnetic field signal interference around the car, and the smart key cannot work normally. Parking the car elsewhere can solve the problem .
door not closed : This can also happen when car owners leave the car without closing the door properly. Just re-close the car door .
