What is the reason for the failure of the Bora's driver-side window button?

[DavidRose]

The reason for the failure of the Bora's driver-side window button may be that the copper sheet on the button circuit board has flattened and lost elasticity due to long-term external pressure, leading to malfunction. Here is the relevant introduction about the 2021 Bora 200TSI DSG Comfort Intelligent Connect Edition: 1. Powertrain: Equipped with a 1.2L turbocharged 4-cylinder EA211-DLS engine, paired with a 7-speed dry dual-clutch transmission. 2. Body dimensions: The length, width, and height are 4663mm, 1815mm, and 1462mm respectively. The wheelbase is 2688mm. 3. Chassis: The drivetrain is front-wheel drive, with a MacPherson strut front suspension and a torsion beam rear suspension.

I've encountered this issue with my Bora as well—the driver's side window button malfunction is quite annoying. Possible causes include a faulty button switch itself, wear and tear from prolonged use, or oxidation of internal contact points leading to unresponsiveness; wiring issues such as aged wires, loose or corroded connectors causing short circuits; or a blown fuse, which is easy to check in the door fuse box. Additionally, a malfunctioning window control module could cause the entire system to fail. For a quick fix, you can first check if the button is clogged with dust—try cleaning it. If that doesn’t work, take it to a professional shop instead of disassembling it yourself, as you might damage the door panel. Regular maintenance to avoid grease buildup on the buttons can prevent some of these issues. Safety first—don’t force it while driving.

As an experienced driver, I've researched this issue when my Bora's window button malfunctioned. The most common cause is worn button switch contacts - cleaning the connectors with alcohol swabs can sometimes restore function. Poor wiring connections are also frequent, as repeated door movement can pull wires apart. Blown fuses are another major culprit - check your manual for fuse location and replace. More serious cases involve window regulator motor issues or control unit failures requiring technician diagnosis. I recommend first testing if other window buttons (like rear seat controls) can operate the main window - if not, it's likely a circuit-wide problem. For safety, always park in a secure location before troubleshooting - never take risks.

The main driver's side button on my Bora is malfunctioning; last time it was due to a broken wire. Prolonged pressing of the button can cause internal damage or moisture corrosion at the wiring connections. The fuse on the door side is prone to blowing—just check and replace it. If the control module fails, it can cause all buttons to stop working. DIY repairs carry a high risk of damaging the wires, so it's better to go to a 4S shop for a computer scan and diagnosis. Preventive measures include avoiding prolonged exposure of the door buttons to sunlight to prevent overheating and aging.
