The most common reasons a 2017 Mitsubishi Mirage 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 Mitsubishi Mirage?

When your 2017 Mitsubishi Mirage's AC isn't functioning properly, it's crucial to start with a systematic diagnostic approach. Begin by checking the thermostat settings to ensure it's set lower than the current room temperature, as this is necessary for the AC to activate. Next, inspect the air filters; if they are dirty or clogged, they can significantly hinder airflow and cooling efficiency, so replacing them may be necessary. After that, verify that the AC controls are correctly set to the cooling mode and that the system is powered on. Low refrigerant levels can also lead to inadequate cooling, so it's wise to check these levels and consider having a professional recharge the system if they are low. Additionally, look for any visible signs of refrigerant leaks around the AC components, as these will need to be addressed by a qualified technician. Finally, ensure that the compressor is engaging properly when the AC is activated, as this component is essential for the system's operation. By following these steps, you can effectively diagnose common AC issues in your Mitsubishi Mirage and determine whether further professional assistance is needed.

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

When the air conditioning system in a 2017 Mitsubishi Mirage ceases to function, it can be frustrating, especially during hot weather. One of the most frequent culprits is low refrigerant levels, which can occur due to leaks or insufficient charging, preventing the system from cooling effectively. Another common issue is a faulty compressor; if the compressor is not engaging or is damaged, it will fail to circulate refrigerant, leading to inadequate cooling. Electrical problems, such as blown fuses or faulty wiring, can also disrupt the AC's operation, making it essential to check these components. Additionally, a clogged or leaking condenser can hinder the system's ability to dissipate heat, while malfunctioning cooling fans can exacerbate cooling issues by failing to draw air through the condenser. By understanding these potential problems, DIYers can better diagnose the issue and take appropriate steps to restore their vehicle's AC functionality.

How urgent is it to repair the non-functioning AC in a 2017 Mitsubishi Mirage?

Repairing the non-functioning AC in your 2017 Mitsubishi Mirage is an urgent matter that should not be overlooked. The discomfort of driving without air conditioning can quickly escalate, especially during sweltering summer months, making long trips unbearable and potentially unsafe. Moreover, the health risks associated with extreme heat are significant; individuals, particularly children, the elderly, and those with pre-existing health conditions, are especially vulnerable to heat-related illnesses. Beyond immediate comfort and health concerns, neglecting the AC repair can adversely affect your vehicle's resale value. A car with a malfunctioning AC is less appealing to potential buyers, which could lead to a lower trade-in value. Additionally, operating your vehicle with a faulty AC system can place undue strain on the engine, potentially leading to more severe mechanical issues down the line. Therefore, addressing the AC problem promptly is essential not only for your comfort and safety but also for the long-term health of your vehicle.
