The most common reasons a Audi S5 window won't go up or down are window's electrical system such as a fuse or relay, a broken window motor, or a broken window regulator.

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
If the door window motor fails, the window may not open or close, or it may operate intermittently. Traditionally, problems with power windows were caused by faulty switches or electrical wiring - especially the wires running between the door and the vehicle body that are subjected to repeated flexing. In these cases, the window might operate intermittently when the door is opened and closed. While this may still be the case on newer cars, it is increasingly common to find window motor problems that originate with a control module. Still, the switches and wiring should be checked thoroughly before replacing a window motor.
If one of the windows in a vehicle will not open or close properly, a failing door window regulator might be the cause. A window that is moving intermittently, or one that gets stuck on the way up or down, could also indicate a broken regulator. Other symptoms might include a clicking, chattering, or grinding noise when the window moves. In some cases a severely damaged window regulator could cause the window to drop inside the door.
When a switch can not make contact and close the circuit, the window cannot be raised and lowered. If the switch on the driver's door will not raise or lower the window in question, but the switch on the corresponding door works just fine, this is a good indication that there is a switch failure. This works the other way around, as well. If the switch on the door does not cause the window to function, but the driver's switch does, that is an indication of a passenger door window switch failure.
Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.
Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.
When troubleshooting window issues in your Audi S5, it's essential to adopt a systematic diagnostic approach. Begin by checking the simplest potential causes, such as the fuse and relay associated with the window system. If these components are functioning correctly, proceed to inspect the window motor and regulator for any signs of failure or open circuits, especially if you encounter specific error codes. A common fix involves resetting the window by holding the switch in the up position for about ten seconds after the window is fully closed, which can often resolve minor glitches. If the window remains unresponsive, further investigation into the electrical system may be necessary. By methodically addressing these areas, you can effectively identify and resolve window issues, ensuring your Audi S5 operates smoothly.
When your Audi S5 window won't go up or down, it's crucial to approach the problem methodically to identify the underlying issue. Start by examining the electrical system, as a blown fuse or a malfunctioning relay is often the primary culprit behind window failures. If the electrical components are intact, the next step is to assess the window motor; a defective motor can completely halt window movement. Additionally, inspect the window regulator, as any damage here can obstruct the window's operation. For newer Audi models, don't overlook the possibility of needing a software update from the dealership, which can rectify various electronic functions tied to window performance. If the window struggles to close properly, recalibrating it may provide a solution; this involves fully closing the window and holding the switch in the up position for a few seconds. For those who enjoy DIY projects, many Audi S5 owners have successfully reprogrammed their windows or replaced faulty components on their own. By systematically checking these areas, you can effectively troubleshoot and potentially resolve the window issue in your Audi S5.
When dealing with a malfunctioning window in your Audi S5, it’s crucial to understand the urgency of the situation. Ignoring symptoms such as a window that won’t open or close properly can lead to more significant problems down the line, including potential damage to the window motor or regulator. Additionally, if the window bounces back when attempting to close, it may indicate a safety feature is triggered due to resistance, which could pose a risk if the window inadvertently opens while driving. Furthermore, a faulty electrical system, such as a blown fuse or malfunctioning switch, can compromise not only the window's functionality but also the overall safety of the vehicle. Addressing these issues promptly not only ensures your comfort and convenience but also prevents costly repairs and enhances your driving safety. Therefore, if you notice any irregularities with your Audi S5 windows, it’s advisable to investigate the cause and take action before the problem escalates.
