What is the reason why the driver cannot control the passenger window lifting?

The reason why the driver cannot control the passenger window lifting may be due to motor overheating protection. To protect the power supply circuit, most window lift motors have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window lift to malfunction. In this case, simply wait for the motor to cool down. Relevant information about the car window is as follows: 1. Introduction: The car window is an important part of the entire vehicle body, designed to meet the needs of interior lighting, ventilation, and the visibility of the driver and passengers. 2. Window names: Depending on the installation position of the glass, car windows can be categorized as front and rear windshields, side windows, and door windows. The design, structure, and quality of the windows significantly affect the driver's visibility, passenger comfort, exterior aesthetics, and aerodynamic characteristics.
I've been driving for decades and have seen many window issues. When the driver's side can't control the passenger window, the most common problem is with the switch itself - internal wear or poor contact in the button causing no response when pressed. It could also be wiring issues like aged/broken wires or short circuits preventing current flow. Another possibility is the passenger window function being locked, like some cars' child safety locks being accidentally activated. If the passenger side can operate its window normally, then definitely the master switch is faulty; if neither works, maybe a fuse is blown. I suggest first testing the passenger side switch, then checking if the driver's button is loose. If you can't fix it yourself, go to a repair shop immediately - don't delay as malfunctioning windows affect driving safety.
This is a common issue when helping others with car repairs. Typically, the main control switch assembly fails, causing the buttons to stop working, or the wire connections corrode and break, preventing the signal from reaching the passenger-side window. A blown fuse is also a factor, as abnormal current triggers the protection circuit to cut off power. Another issue in modern cars is the control module, whether due to software bugs or hardware burnout. It's recommended to first check the relevant fuse in the fuse box and try replacing it with a spare. Then, press the main switch to feel for any stiffness. Those with strong DIY skills can remove the panel to clean the contacts, but avoid forcing anything to prevent damage. Safety first—address the issue early to avoid emergencies where the window won't open.
