Reasons Why the Passenger Window is Not Controlled by the Master Switch?

It may be due to a malfunction in the driver's window switch. Below is relevant information: Automobile: According to the latest national standard in China, 'Terms and Definitions of Types of Automobiles and Trailers,' an automobile is defined as a non-track vehicle powered by an engine, with four or more wheels, primarily used for: transporting people and/or goods; towing vehicles that carry people and/or goods; and for special purposes. Automobile Classification: Domestic automobile brands include Wuling, Baojun, Hongqi, Changan, Great Wall, Chery, Geely, Roewe, BYD, etc. Foreign automobile brands include Toyota, Volkswagen, Audi, Mercedes-Benz, Hyundai, Kia, Peugeot, Cadillac, etc.
I once had a similar issue with my car where the passenger window near the driver's side wouldn't respond no matter how much I pressed the button. It turned out to be a loose wiring connection. In the window system, the main switch controls the passenger window by sending signals through wires. If the wires are corroded or the plug connection is poor, the signal gets cut off. Another possibility is a faulty main switch itself, where the contacts are severely worn and unresponsive when pressed. A common reason could also be the activation of the child lock, a safety feature that disables the main control, so you should check the door settings. A blown fuse can also cause a power failure. In my case, after removing the interior trim, I found a section of wire with exposed insulation causing a short circuit, and it worked fine after repair. I recommend starting with simple checks, like using a multimeter to test the continuity of the wiring, instead of guessing and wasting money. Driving safety is crucial; a poorly closed window can be dangerous at high speeds due to wind gusts, so it's best to get it fixed promptly when issues arise.
