The most common reasons a 2020 Subaru Ascent 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.
  • Fuse, Relay or Electrical System: A blown fuse or a faulty relay can disrupt the electrical circuit, causing components to fail or operate intermittently.
  • Window Motor: A faulty window motor or a broken window regulator can prevent the window from moving up or down properly.
  • Window Regulator: A faulty window regulator can cause the window to become stuck or operate erratically due to worn gears or a broken cable.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2020 Subaru Ascent window won't go up or down?

Common Repairs

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.

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.

What are the steps to diagnose a non-functioning window in a 2020 Subaru Ascent?

To effectively diagnose a non-functioning window in a 2020 Subaru Ascent, it’s essential to adopt a systematic approach that prioritizes simpler solutions before delving into more complex diagnostics. Start by checking the window switch, as a malfunctioning switch is often the simplest explanation for window issues. If the switch is operational, the next step is to inspect the fuse box for any blown fuses related to the window; replacing a blown fuse is a quick and easy fix that can save you time and effort. Following this, examine the wiring connected to the window motor for any signs of damage or disconnection, as compromised wiring can prevent the window from functioning properly. If the wiring appears intact, utilize a multimeter to test the window motor for power and ground, which will help you ascertain whether the motor itself is at fault. Finally, consider the condition of the window tracks; debris or insufficient lubrication can impede window movement, so cleaning and applying lubricant can often restore functionality. By following this diagnostic method, you can efficiently identify and resolve the issue with your window, ensuring a smoother and more effective repair process.

What are the common problems that could cause the window in a 2020 Subaru Ascent to stop working?

When dealing with a non-functioning window in a 2020 Subaru Ascent, it's essential to understand the common problems that could be at play. One of the primary culprits is a faulty window regulator, which is responsible for the mechanical movement of the window. Over time, this component can wear out, leading to issues with the window's ability to move up or down. Another potential issue is a defective window motor; if this motor fails, the window will not respond to the switch commands, leaving it stuck in place. Additionally, electrical problems such as a blown fuse or damaged wiring can disrupt the window's operation, making it crucial to inspect the fuse box and wiring for any signs of trouble. A malfunctioning window switch can also be a factor, as it may fail to send the correct signals to the motor, preventing the window from functioning properly. Lastly, if the window has come off its track, it may get stuck or move unevenly, often due to wear and tear or obstructions in the window mechanism. By identifying and addressing these common issues, you can effectively troubleshoot and resolve window problems in your Subaru Ascent, making it a manageable DIY project.

How urgent is it to fix the malfunctioning window in my 2020 Subaru Ascent?

When faced with a malfunctioning window in your 2020 Subaru Ascent, it is crucial to recognize the urgency of the situation. A window that fails to operate correctly can compromise your safety, especially if it remains open, exposing you to potential hazards on the road and making it difficult to communicate effectively in various driving conditions. Additionally, an inoperable window can leave your vehicle vulnerable to adverse weather, allowing rain, snow, or extreme temperatures to infiltrate the cabin, which can lead to interior damage and affect sensitive electronic components. Security is another significant concern; a window that does not close properly can make your car an easy target for theft or vandalism, putting your belongings at risk. Lastly, addressing window issues promptly is essential for maintaining the resale value of your Subaru Ascent, as prospective buyers may be deterred by visible defects. Therefore, it is advisable to prioritize repairs to ensure your safety, protect your vehicle from damage, maintain security, and preserve its value.
