The most common reasons a 2017 Subaru Impreza AC isn't working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.
  • Refrigerant Leak: A refrigerant leak can occur due to damaged hoses, seals, or connections, resulting in decreased cooling efficiency in the air conditioning system.
  • Climate Control Electrical Issue: A faulty climate control module or a blown fuse could be causing the electrical issues in the climate control system.
  • AC Compressor: A faulty AC compressor may be due to a lack of lubrication, electrical issues, or internal mechanical failure, resulting in inadequate cooling performance.
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.

What are the initial steps to diagnose the AC issue in a 2017 Subaru Impreza?

To effectively diagnose the AC issue in your 2017 Subaru Impreza, start by checking the air filters, as dirty or clogged filters can significantly restrict airflow and diminish cooling performance. Next, inspect the refrigerant levels; low levels may suggest a leak, which is crucial to address for optimal AC function. Following this, examine the AC compressor, as a malfunctioning compressor can lead to inadequate cooling. It's also important to test the thermostat, since a faulty thermostat can cause the system to blow hot air instead of cold. Additionally, look for any visible leaks in the AC system, as these can severely impact efficiency. Finally, assess the electrical components, ensuring that all connections are secure and functioning properly. By systematically following these steps, you can effectively narrow down the potential causes of your AC issues and take the necessary actions to restore comfort in your vehicle.

What are the common problems that could cause the AC to stop working in a 2017 Subaru Impreza?

When troubleshooting the air conditioning system in a 2017 Subaru Impreza, it's essential to understand the common problems that may lead to a malfunction. One of the primary issues is low refrigerant levels, which can significantly hinder the system's cooling efficiency. If the refrigerant is low, it may indicate a leak that needs to be addressed. Another frequent culprit is a faulty compressor; if the compressor isn't functioning correctly, it won't circulate the refrigerant effectively, resulting in poor cooling performance. Additionally, electrical issues such as blown fuses or damaged wiring can disrupt the AC's operation, making it crucial to inspect these components. Clogged or leaking condensers can also impede airflow and cooling, so checking for blockages or leaks is vital. Lastly, ensure that the cooling fans are operational, as broken fans can lead to insufficient airflow through the system. By systematically examining these areas, DIYers can diagnose and potentially resolve AC issues in their Subaru Impreza, restoring comfort during warmer months.

How urgent is it to address the non-functioning AC in my 2017 Subaru Impreza?

When your 2017 Subaru Impreza's air conditioning system fails, it’s essential to recognize the urgency of the situation. While it may not seem like an emergency, neglecting a malfunctioning AC can lead to discomfort during hot weather, which can distract you from driving and affect your overall experience. Moreover, a faulty AC can compromise the air quality inside your vehicle, potentially leading to health issues over time. Additionally, addressing the problem promptly can help maintain your car's resale value, as prospective buyers often look for well-maintained vehicles. Ignoring the issue can also result in more severe damage, leading to costly repairs that could have been avoided with early intervention. Therefore, it’s advisable to assess and resolve any AC issues as soon as they arise to ensure a comfortable, safe, and healthy driving environment.
