What is the reason for the non-functioning left rear window regulator of the Haval H6?

Haval H6 left rear window regulator not working may be caused by a detached ground wire of the combination switch, detached main power wire, poor relay contact, damage, or poor contact or failure to close the lock switch. Solution: You need to drive the car to a 4S shop to check the circuit or replace the window regulator. Power Window: It is a device that uses the vehicle's power source to drive the window regulator motor, causing the regulator to move up and down, thereby moving the window glass up and down to achieve automatic opening and closing of the window. Power windows allow the driver or passengers to sit in their seats and use a switch to automatically raise or lower the door glass, replacing the traditional method of turning a crank to move the glass. This makes the window movement lighter, more comfortable, and automated.

As a friend who often repairs cars, I've encountered many cases where the rear left window of the Haval H6 won't move. There are three main causes: first, the switch is broken—the button doesn't respond when pressed, and rainwater seeping in can easily corrode the contacts; second, the window motor is aging, making a buzzing sound but not moving when opening the window—this motor tends to fail after prolonged use; third, wiring issues, such as worn-out wires inside the door or loose connectors, leading to short circuits or open circuits. Additionally, blown fuses are common, especially when the circuit is overloaded—check the corresponding position in the fuse box to verify. A stuck window regulator mechanism is also a potential issue, as lack of lubrication in the tracks can cause the glass to jam. It's recommended to first test the switch and replace the fuse. If that doesn't work, the door panel will need to be removed to inspect the wiring and motor. Address the issue promptly, as neglecting it can compromise safety and even affect the door lock. The Haval H6's door panel design is compact, making it prone to minor issues, so visiting a professional repair shop is the most hassle-free solution.

When driving my Haval H6, I experienced a similar issue with the rear left window. It was often due to a blown fuse, which could be fixed by replacing it with a new one for just a couple of dollars. Switch failure is also common, where there's no response when pressing the button, requiring the replacement of the entire switch assembly. If the motor is faulty, you'll hear noise when operating the window but it won't move, possibly necessitating a new window regulator. Loose or corroded wiring connections are more likely to occur after rain, so it's important to check the wiring inside the door. For prevention, avoid opening the window in rainy weather, regularly clean the glass tracks, and apply some anti-rust spray. Don't attempt to forcibly repair the Haval's electronic system yourself, as it could damage more components. First, test the switch, then use tools to check the fuse—simple steps, but safety comes first.

When dealing with window issues, I usually start with the simplest solutions. First, check if the switch button is broken or the contacts are dirty, then test whether the fuse is blown. A faulty motor often produces a humming sound but the window won't move, requiring replacement. Aging or short-circuited wiring can cause an open circuit—use a multimeter to measure voltage and locate the break point. The window regulator mechanism in Haval H6 doors tends to get stuck, which can often be resolved with lubrication. For DIY repairs, disconnect the battery cables and remove the door panel; replacement parts are easily available online. Take your time during the process to avoid damaging the clips.
