The most common reasons a 2017 Toyota 86 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 diagnostic steps to take when the AC isn't working in a 2017 Toyota 86?

When your AC isn't functioning in a 2017 Toyota 86, start by checking the thermostat settings to ensure it is set to a cool temperature and that the AC is activated. If the settings are correct, inspect the air vents to confirm that air is flowing; a lack of airflow may indicate a problem with the blower motor or a blockage in the ducts. Next, listen for any unusual noises when the AC is running, as these sounds can signal a malfunctioning component. It's also essential to check the refrigerant levels using a pressure gauge, as low levels can result in warm air blowing from the vents. Additionally, look for any visible signs of leaks, such as oily residue around connections, which can lead to refrigerant loss. Finally, ensure that the compressor is engaging properly when the AC is turned on. If these steps do not resolve the issue, it may be time to consult a professional for a more thorough diagnosis.

What are the common problems that could cause the AC to stop working in a 2017 Toyota 86?

When the air conditioning system in your 2017 Toyota 86 stops functioning, it can be frustrating, especially during hot weather. One of the first things to check is the refrigerant level; low refrigerant can significantly impair the system's cooling ability. If the refrigerant is adequate, the next step is to inspect the compressor, as a faulty compressor can prevent the system from circulating refrigerant properly. Additionally, electrical issues such as blown fuses or damaged wiring can disrupt the AC's operation, so examining these components is crucial. Clogged or leaking refrigerant lines can also hinder performance, so look for any visible signs of damage or blockages. Furthermore, a damaged condenser can affect heat transfer, leading to poor cooling performance, while a malfunctioning blower motor may result in weak airflow from the vents. By systematically checking these common problems, you can identify the issue and determine whether a DIY fix is possible or if professional assistance is needed.

How urgent is it to address the non-functioning AC in a 2017 Toyota 86?

When faced with a non-functioning AC in your 2017 Toyota 86, it is crucial to recognize the urgency of the situation. The discomfort caused by a malfunctioning air conditioning system can significantly detract from your driving experience, especially during hot weather or long trips. More than just a matter of comfort, a faulty AC can also pose safety risks; for instance, if the windows fog up due to humidity, visibility can be compromised, leading to dangerous driving conditions. Additionally, neglecting AC issues can result in further damage to the system, potentially escalating repair costs and complicating the problem. Timely repairs not only help maintain a safe and pleasant driving environment but also protect the overall condition of your vehicle, which is essential for preserving its resale value. By addressing the AC issue promptly, you ensure a more enjoyable and secure driving experience while safeguarding your investment in the long run.
