The most common reasons a 2019 Subaru WRX STI 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 2019 Subaru WRX STI 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 2019 Subaru WRX STI?

To effectively diagnose a non-functioning window in a 2019 Subaru WRX STI, begin with the simplest solutions before progressing to more complex issues. Start by checking the window switch, as a malfunctioning switch is often the root cause of the problem. If the switch appears to be operational, inspect the fuse associated with the window; a blown fuse can easily disrupt functionality. Next, test the window motor to ensure it is receiving power; if it isn’t, the motor may need replacement. Following this, examine the window regulator for any signs of damage or wear, as a faulty regulator can impede window movement. Additionally, check for any wiring issues, such as frayed wires or loose connections, which could be affecting the window's operation. If these steps do not resolve the issue, it may be time to consult a professional mechanic who specializes in Subaru vehicles for a thorough diagnosis and repair. By systematically addressing these potential issues, you can effectively troubleshoot the non-functioning window.

What are the common problems that could cause the window in a 2019 Subaru WRX STI to stop functioning?

When dealing with a non-functioning window in a 2019 Subaru WRX STI, 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 it fails, the window may become stuck. Additionally, the power window motor, responsible for driving the regulator, can also malfunction, preventing the window from responding to the switch. Electrical issues, such as blown fuses or damaged wiring, can disrupt the power supply to the window system, leading to operational failures. Another potential issue is a malfunctioning window switch, which may not send the correct signals to the motor. Furthermore, if the window has come off its track, it can become misaligned, hindering its movement. Lastly, any damage to the window glass itself, like cracks or chips, can also impede functionality. By identifying these common problems, DIYers can effectively troubleshoot and resolve window issues in their Subaru WRX STI.

How urgent is it to address the malfunctioning window in my 2019 Subaru WRX STI?

Addressing a malfunctioning window in your 2019 Subaru WRX STI is crucial for several reasons. First and foremost, a window that fails to operate correctly can significantly impair your visibility and ventilation while driving, creating a safety hazard for you and other road users. Additionally, a malfunctioning window can leave your vehicle vulnerable to theft, as it may not close securely, allowing easy access for potential intruders. Furthermore, neglecting this issue can lead to further complications, such as damage to the window mechanism or surrounding components, which could escalate repair costs. Therefore, it is essential to prioritize fixing your window promptly to ensure your safety, maintain your vehicle's security, and avoid more extensive repairs in the future.
