Power Window System Failure: Complete Control Loss

Had the same problem with my 2019 Golf GTE Hybrid last winter. With some basic car maintenance experience, I first tried the basic fixes like checking fuses and battery, but nothing worked. The window control module was completely dead, no response from any window switches or controls. Took it to an independent workshop specializing in VW electronics. Their diagnostic revealed a defective power window switch in the driver door, which had caused the entire window mechanism to fail. Total repair cost was 200€ including parts and labor. The window motor and window track were fine, but the main control unit needed replacement. Since the fix, all window controls work perfectly. For a more specific diagnosis of your issue, could you share: Does the problem affect all windows or just specific ones, Are there any unusual sounds when pressing the switches, Did it stop working suddenly or gradually, Have you noticed any other electrical issues This would help determine if you are dealing with the same window control system failure I experienced. These window mechanism problems are somewhat common in recent Golf models, but usually fixable without major complications.

Latest service was at 99000km. These window control issues are definitely frustrating. The problem affects all 4 windows simultaneously, my experience matches yours completely. No sounds at all when pressing any switch. Had it checked with a diagnostic tool and error code B128900 shows up consistently. The window motor and window regulator assembly seem mechanically sound, but the complete electrical failure points to a control module issue. Pretty reassuring to hear your repair costs were reasonable. I might try the same approach with a specialized workshop since the component pricing you mentioned seems fair, especially compared to dealer rates. I will try to get it fixed this week and report back with the results in case anyone else runs into similar power windows problems with their Golf.

Thanks for the update and those details about your window control situation. Yes, that error code B128900 is exactly what I encountered when my windows stopped working. Looking at the similarities in our cases, all windows affected and complete electrical silence, it does point to the same control module failure I experienced. Our window motor setups are nearly identical since these Golf hybrids share the same power window architecture. Just make sure the workshop does a full system diagnostic before replacing parts. In my case, they initially thought the window regulator was the problem, but testing revealed it was purely an electrical control issue. A good tip for others reading: always get the error codes checked first, as window mechanism problems can stem from either mechanical or electrical sources. The complete shutdown of all automotive window functions usually indicates a control module problem rather than individual window motor failures. The 200€ repair has proven reliable, no issues with the power windows for over a year now. The window control system has worked flawlessly since the module replacement. Looking forward to hearing how your repair turns out.

I appreciate the helpful follow-up details. The window regulator issue with my Golf Hybrid is being fixed tomorrow morning. The shop confirmed they have dealt with similar power windows failures, so I am hopeful for a straightforward repair like yours. The complete electrical shutdown of all windows pointed them toward checking the control module first, before exploring any mechanical window motor problems. They quoted around 250€ for parts and labor, which seems reasonable considering the diagnostic work needed. The matching error code and identical symptoms definitely helped narrow down the issue. Door panel removal and window regulator access is apparently straightforward on these models, so labor costs stay manageable even with complete control module replacement. Will update once everything is sorted to help others who might face similar automotive repair challenges with their window control systems. Thanks again for sharing your repair experience, it helped confirm I am on the right track with this fix.
