The most common reasons a 2018 Subaru BRZ 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 2018 Subaru BRZ 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 2018 Subaru BRZ?

To effectively diagnose a non-functioning window in your 2018 Subaru BRZ, begin with the simplest solution by testing the window switch. A malfunctioning switch is often the culprit and can be easily replaced if found faulty. Next, inspect the fuse box for any blown fuses associated with the window system; replacing a blown fuse is a straightforward fix that can restore functionality. If these initial checks do not resolve the issue, examine the wiring connected to the window motor for any signs of damage or disconnection, as faulty wiring can prevent the motor from receiving power. Utilize a multimeter to test the window motor itself, ensuring it is receiving the necessary power and ground; if not, the problem may lie within the wiring or switch. Finally, assess the window regulator for any signs of wear or damage, as a faulty regulator will require replacement to restore proper window operation. By following this diagnostic approach, you can systematically identify and address the issue, making your DIY repair process more efficient and effective.

What are the common problems that could cause the window in a 2018 Subaru BRZ to stop working?

When addressing window issues in a 2018 Subaru BRZ, it's important to recognize the common problems that may be causing the malfunction. A faulty window regulator is often the primary issue, as it directly affects the mechanical movement of the window and can deteriorate over time. Additionally, a defective window motor can prevent the window from responding to the switch, leaving it stuck in place. Electrical problems, such as blown fuses or damaged wiring, can also disrupt the window's operation, making it essential to inspect these components for any signs of failure. Moreover, if the window switch is malfunctioning, it may only allow the window to move in one direction or not at all, indicating a need for replacement. Lastly, if the window has come off its track, it may require realignment to function properly again. By methodically examining these potential issues, you can effectively diagnose and resolve the window problems in your Subaru BRZ, ensuring smooth operation once more.

How urgent is it to address the malfunctioning window in my 2018 Subaru BRZ?

Addressing a malfunctioning window in your 2018 Subaru BRZ is crucial for several reasons. First and foremost, a window that fails to close properly can compromise your vehicle's security, making it an easy target for theft or vandalism. Additionally, if you encounter inclement weather, an open or malfunctioning window can lead to water damage, mold growth, and deterioration of your car's interior, including upholstery and electronic components. Furthermore, visibility is paramount for safe driving; a malfunctioning window can obstruct your view, particularly during rain or snow, increasing the risk of accidents. Lastly, delaying repairs can exacerbate the problem, potentially leading to more extensive damage to the window mechanism and surrounding parts, which can result in higher repair costs down the line. Therefore, it is essential to prioritize fixing your window promptly to maintain your vehicle's safety, security, and overall functionality.
