The most common reasons a 2018 Subaru WRX 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.

How much does it cost to fix a 2018 Subaru WRX 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 steps should I take to diagnose the issue with my 2018 Subaru WRX window that won't go up or down?

When faced with a window that won't go up or down in your 2018 Subaru WRX, it's essential to adopt a systematic diagnostic approach. Begin by checking the window switch, as a malfunctioning switch is often the simplest issue to resolve. If the switch appears to be working, proceed to inspect the fuse related to the window operation; a blown fuse can easily disrupt functionality. Next, test the window motor to ensure it is receiving power and functioning correctly, as this component is crucial for window movement. If the motor checks out, examine the window regulator for any signs of damage or malfunction, as it plays a vital role in the window's operation. Additionally, look for any obstructions that may be blocking the window's path, as debris can often cause unexpected issues. Finally, inspect the wiring connected to both the window motor and switch for any damage or loose connections, as faulty wiring can lead to operational failures. By following this structured approach, you can effectively diagnose and potentially resolve the issue with your Subaru WRX window. If the problem persists after these checks, seeking assistance from a professional mechanic may be necessary for more complex repairs.

What are the common problems that could cause the window in a 2018 Subaru WRX to not go up or down?

When dealing with a window that won't go up or down in a 2018 Subaru WRX, 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 crucial for the window's movement. If this component is damaged, it can hinder the window's operation. Additionally, the power window motor may be experiencing issues; if this motor is worn out or defective, it won't provide the necessary power for smooth window movement. Electrical problems are another frequent cause, including blown fuses or faulty wiring, which can disrupt the window's functionality. Furthermore, a malfunctioning window switch can prevent the window from responding to commands, making it seem as though the window is stuck. Lastly, if the window has come off its track, it will not move properly, which can occur due to wear and tear or physical damage. By identifying and addressing these issues, you can effectively troubleshoot and resolve the window malfunction in your Subaru WRX.

How urgent is it to fix the malfunctioning window in my 2018 Subaru WRX?

Addressing a malfunctioning window in your 2018 Subaru WRX is an urgent matter that should not be overlooked. The safety implications are significant; a window that does not close properly can obstruct your view, increasing the likelihood of accidents on the road. Furthermore, an open window can expose your vehicle to harsh weather conditions, allowing rain, snow, or debris to enter, which can damage the interior and create an uncomfortable driving experience. Security is another critical factor; a window that cannot be secured makes your car vulnerable to theft and vandalism, putting your belongings at risk. Additionally, neglecting to fix this issue can negatively impact your vehicle's resale value, as prospective buyers may be deterred by visible malfunctions. Therefore, it is essential to act promptly and repair the malfunctioning window to ensure your safety, protect your investment, and maintain the overall condition of your Subaru WRX.
